Sex Dice
by Jeff
Image text: You roll for initiative, and ... [roll] ... wow, do you ever take it.
In this comic, there are two different groups playing two different dice games. However, the dice got mixed up. Instead of numbers, the first two are supposed to have another die with actions on them, as seen in the last panel. The "sex" die got mixed in with the kids Dungeons and Dragons set because they did not organize the game cupboard. The four people in the last panel are completely different than the two in the first 3.
The joke in the image text is a play on the word "initiative". In Dungeons and Dragons you roll for initiative for an extra modifier to your roll of the dice. In the image text, they are suggesting that someone accidentally rolled a sex die for initiative. And "take initiative" means to take charge to take command outside of Dungeons and Dragons.

Just a small correction, in D&D initiative refers to the order in which events occur in a given round/encounter. At the beginning of an encounter, each character rolls a die for initiative (adding any appropriate modifiers) and then the character with the highest initiative value takes action first.

The initiative comment is a seperate part of the game to the one happening in the fourth panel. In that panel, the roll was likely an attack or damage roll. Initiative rolls are used to determine the order in which players take their turns – ‘taking initiative’, hence the pun derived from whatever was rolled on the sex die.
