jumpin planes!!!

Five guys were on a plane...a kid, a preacher, a doctor, the captain, and a lawyer. The captain came on the P.A. system and says "Mayday, Mayday! We're going down and there is only four vests on the plane. You guys decide who's staying but I'm jumping now!!!" The doctor says "I've saved lives my whole life so I think that I should get one," so the doctor jumps. The lawyer says "I'm the smartest man in the world. I've solved over nine dozen cases so I'm jumpin' bye!" So the preacher goes up to the kid and says "I've lived a long and happy life and I know I'm going to heaven, so you take the last vest and go." The kid says "No, you grab this one and I'll grab the other one because the smartest man in the world just jumped with my book bag!!!!"
