(Scene: The interior of the family Guy main studio, facing the glass wall behind of which several manatees are nosing floating balls from a big netted collection of balls toward a chute.)
(Seth MacFarlane is watching the manatees at work. At the bottom of the chute is a view-box receptacle wherein five balls have just descended. Seth MacFarlane reads off the five balls.)
Seth MacFarlane: Ipecac Contest, WWI Air Force, Homer Simpson, Bob Belcher, Cleveland Brown." Sounds like a Family Guy joke!
(Cutaway back to the living room where Peter, Brian, Chris and Stewie are having their Ipecac drinking contest which induces a considerable amount of "purging.")
(The puking finally enters a lull and the four appear to be recovering. Lois enters the living room with a big bucket of clam chowder.)
Lois: Okay, who wants chowdah?
Peter, Brian, Chris and Stewie (all puking in unison): Wruaaaugh!
Lois (puts the pot back in the kitchen and turns to the four men): Peter! You and the boys have thrown up all ovah the flooah! And look! You even have vomit on the furnichah -- and all over yourselves, too!
Peter: You think that's bad! Remembah the time I flew the in the World War One Air Force with Homer Simpson, Bob Belcher and Cleveland?
(Cutaway to the scene in the Family Guy - Simpsons crossover show where Cleveland goes down. Again.)
Bob Belcher: (popping up from the rear of the plane): Yeah, we did it!
Homer (angry): What's he doin' here?
Peter (non-chalant): Oh we gotta carry him; he can't fly on his own. We let that other guy try, and look what happened.
(Cutaway to Cleveland's plane, the engine of which just caught fire.)
Cleveland: No, no, no, no, NO!! (as his plane enters its death spiral).Okay, this is my last South Park Family Guy joke. I've run out of ideas! 😁
