If I’d been in this study, I would’ve eaten the marshmallow, stolen all the other kids’ marshmallows, and had my mouth chubby-bunny-stuffed within the first two minutes. Whereas John would have waited, but only because he doesn’t even LIKE sweets.
TEXT OF COMIC:
Hi, Sharon. Hi, Karen. Here, have one marshmallow apiece.
Marshmallows? Why?
I’m doing a scientific study to see if you have self-control and the ability to put long-term goals above immediate gratification. If you go fifteen minutes without eating your marshmallow, I’ll give you another one and you get to eat them both.
Why are you testing both of us?
You’re identical twins. I want to see how much influence genes have.
Are we going to get paid to be your experimental subjects?
I’M PAYING YOU IN MARSHMALLOWS.
MOUSEOVER TEXT: best way to get paid EVER

Bleagh, marshmallows. Got any peanut butter cups?
I think this test would have been a lot more accurate if done with peanut butter cups.
Except for the peanut-allergic kids.
