Engineer's New Bike

An engineering student was riding across campus on a shiny new bike. He ran into a friend of his who said "Wow, that's a great bike! Where did you get it?"

"Well, the darndest thing happened" said the first student. "A girl came riding up to me and got off the bike, threw off all her clothes, and said I could have anything I wanted!"

"Wow," remarked his friend. "That's great! Good move, her clothes probably wouldn't have fit you."
