Ewwwww!
An art director said when he really wants to get little kids to laugh...he tells them about the time when he was 4 and ate a whole can of Spaghetti-o's and then took a bath in his underwear with his 3 year old sister and then threw up the Spaghetti O's in the tub. He says kids can't stop laughing. So I tried his story out on these "big kids" and it didn't make them laugh.
