hobos and lotion are not funny

why does every episode say hobo and lotion like 20 times. like carly will randomly say "lotion!" and the laugh track goes nuts. what the fucck is so goddamn funny about lotion??? does dan schnieder like lotion on his feets?? they do the same with various pastas, mostly spaghetti. according to dan, lotion, hobos, and pasta are the funniest things ever.
