Troublemaker Puns

A boy asks his father if he can go hang out with friends. His dad says, " which friends are you going with?" and the boy replies, "I'm going with Timmy and Bob," so his father asks, "Who is Timmy and who is Bob," the boy says, "Timmy is a short trouble maker, and Bob is also a short troublemaker." The father replied, "I dont want you hanging out with those kids." The boy said, "Why dad?" His dad says, " I dont want you becoming short like them."
