Title text: Also, it's not like anyone actually calls up the Nobel committee to double-check things.
Some pregnancies are different than others, but a universal truth (except in cases of Cesarean section) is that a baby will always exit a woman's body through the vagina. Cueball has put on a white lab coat, posing as an obstetrician to play a prank on Megan, saying that until the second trimester, there's a chance the baby might choose to exit through the anus or mouth. And because he's posing as a doctor, Megan is floored by that claim; presumably she's never heard that before.
The alt-text implies also that in addition to faking being a doctor, he's also faking being a Nobel laureate, on the logic that people will not choose to verify this claim.
- Cueball: Well, until the second trimester, the baby hasn't decided which opening it will exit through.
- Megan: What?
- Cueball: We'll hope for one of the lower ones, so it won't be fighting gravity.
- Did you know you can just BUY lab coats?
