You'd have to ask these two;)
PAP-PAP: Couldn't stomach the spoiled milk
GRANDMA: Gagged on the dead fish
TISTAH: In typical Cass style, she committed to the mind over matter strategy and ate a booger and barf jellybean like they were pieces of chocolate.
TIFF: Still recovering from rotten egg...involuntary spit up
GIDEON: Loved every second of this game...
ISAAC: Threw in the towel after taking a bite of canned dog food
MILES: Was smart enough not to play
FINLEY: Yes, I've said this before, and I will say it again, these people truly are your relatives.
