Bill Fishman: I think Sachel started the sentence and then got distracted thinking about all the things he could eat, and was staring off into the distance, and Rob looked where he was staring.
Susan Anderson: And the reason he isn’t finishing the sentence is that, regardless of how hungry he is or isn’t, he always eats “a horse” when he consumes his dog food.
Joe Blevins: Of course, the complete expression is “eat a horse,” but who wants to eat a horse? Incidentally, I’ve been telling this same joke for years (“I’m so hungry I could EAT!”), and it’s never gotten more than a weak chuckle. Sachel didn’t even get that.
