The teacher [[Miss Lenhart]] warns two small kids using a danger {{w|mnemonic}}

{{incomplete|Created by a DRUNKEN SAILOR'S POISON IVY SNAKE. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
  
However, this is actually a mash-up of three different common danger mnemonics, each of which warn about different hazards.
+
This is a mash-up of three different common sayings: "red touches yellow, dead fellow. Red touches black, happy Jack," "leaves of three, leave them be; berries white, poisonous sight" and "red sky at morning, sailors take warning. Red sky at night, sailor's delight."
  
*Red touches black, that's a friend of Jack; red touches yellow, you're a dead fellow.
+
The combination of the three sayings make it sound somewhat like an ominous prophecy, citing odd, specific conditions under which some unknown disaster will occur- in which case, you probably should get out of there.
  
This mnemonic is intended to help recognize venomous {{w|coral snake}}s, which have brightly colored stripes. Some nonvenomous {{w|king snake}} species have similar striped colors, but in different patterns. '''NOTE THAT THIS MNEMONIC IS NOT ACCURATE, ESPECIALLY OUTSIDE THE EASTERN UNITED STATES WHERE IT WAS ORIGINALLY CREATED'''; many species of coral snake have black stripes touching red stripes, and if the snake has atypical coloration, then the rhyme may still lead to misidentification even in the right region. The safest course of action is to avoid any snake with the warning colors of red, yellow/white, and black stripes. Another corruption of the same warning features in [[1604: Snakes]].
+
The adult refers to three different sayings that remind people how to recognize dangerous things or situations. If all are true at once, then things must be especially bad. The sayings are:
  
*Leaves of three, leave them be; berries white, poisonous sight. (Alternatively, "berries white, run in fright" or "hide from sight.")
+
*'''Red touches yellow, kills a fellow.''' This is a saying for how to recognize a venomous coral snake, which has red, black, and yellow stripes, with the red and yellow stripes adjacent. A nonvenomous king snake also has red, black, and yellow stripes, but the black stripes separate the red and yellow ones. Note that this identification is only accurate in eastern North America, coral snakes in other parts of the world sometimes have black stripes touching red stripes. The safest course of action is to avoid any snake with the warning colors of red, yellow/white, and black stripes.
 +
*'''Leaves of three, leave them be''' is used to identify poison ivy (on the east coast) and poison oak (on the west coast) from its many lookalikes, such as the Virginia creeper in [[443: Know Your Vines]].
 +
*'''Red sky at morning, sailor take warning.''' The {{w|Red sky at morning|mnemonic}} predicts bad/good weather conditions based on a particularly red sunrise/sunset. It is predictive at {{w|middle latitudes}} where the prevailing winds go from west to east.  Regions of higher air pressure will cause a particularly red sky at sunrise/sunset, so a red sky in the evening indicates a high pressure system is coming in from the west with its calmer weather, while a red sky in the morning indicates a low pressure front coming in (usually with rain/rougher weather). In some countries (such as the United Kingdom), the saying mentions shepherds rather than sailors.
  
This mnemonic is used to identify {{w|poison ivy}} and {{w|poison oak}} throughout much of North America. These plants both produce an oily surface resin called urushiol, which causes an allergic reaction in the majority of people. Touching either plant can result in contact dermatitis, which can be severely itchy or painful. If burned, the urushiol can be inhaled, causing lung irritation.  While rarely serious, these reactions are often severely unpleasant and can last for weeks, so avoiding the plants is well advised. Both plants generally grow three leaves at the end of each branch, and grow berries that turn white when ripe.  The mnemonic helps in remembering this characteristic to distinguish them from similar-looking but harmless vines. See [[443: Know Your Vines]].
+
The title text refers to the myth of '''Beer before liquor, never been sicker; liquor before beer, you're in the clear''', or one of various other colloquial folk variations that clearly already inspired [[2422: Vaccine Ordering]]. Unlike the first three mnemonics which are genuinely useful for avoiding danger, this one does not have any truth behind it - unless the order affects how ''much'' you drink. Perhaps the title text is a warning against getting drunk around deadly snakes, and poison ivy, in bad weather.
  
*Red sky at night, sailor's delight; red sky in the morning, sailors take warning.

This {{w|Red sky at morning|mnemonic}} predicts bad/good weather conditions based on a particularly red sunrise/sunset. It is predictive at {{w|middle latitudes}} where the prevailing winds go from west to east.  Regions of higher air pressure will cause a particularly red sky at sunrise/sunset, so a red sky in the evening indicates a high pressure system is coming in from the west with its calmer weather, while a red sky in the morning indicates a low pressure front coming in (usually with rain and rougher weather). In some countries (such as the United Kingdom), the saying mentions shepherds rather than sailors. Randall actually wrote a [https://www.nytimes.com/2019/08/13/science/what-makes-a-red-sky-at-night-and-at-morning.html newspaper article] explaining this phenomenon.

==Transcript==
 
 
Combining all three sayings sounds particularly ominous. It implies that a person is involved with a situation simultaneously involving coral snakes, poison ivy, and potentially nasty weather.  In such a case, Miss Lenhart advises the children to "just get out of there", implying that the situation is too dangerous to try to deal with.
 
 
 
The title text refers to another mnemonic: 'Beer before liquor, never been sicker; liquor before beer, you're in the clear.' Unlike the first three mnemonics, which are genuinely useful for avoiding danger, this one is [https://www.nytimes.com/2006/02/07/health/the-claim-mixing-types-of-alcohol-makes-you-sick.html largely a myth], as the order in which you drink alcohol is unlikely to impact how sick you become. However, whether the mnemonic is true or not, testing it would involve multiple drinks of alcohol, which would be ill-advised when facing a dangerous situation, particularly one as bizarre and complex as implied in this strip.
