This is a really funny video taken from Family Guy season 4 episode 8 where Peter challenges Brian, Chris and Stewie to a vommiting contest where the last person not to vomit is the winner. In order to do this they first each drink a bottle of IPECAC – a vomit inducing drink used to treat victims of poisoning! Everyone feels fine for the first few moments until they all start vommiting uncontrollably, with Chris emerging victorious before vommiting himself!
Then funniest moments in my opinion are when Stewie is curled up in the fetal position, and when Brian asks Peter to hold back his ears while he vomits only for Peter to vomit on his own head. Disgusting, but very amusing! The scene ends when Lois enters the room asking “who wants chowder?” before they all vomit again.
