Jamie Farr
This guy is definitely as crazy as the character he played on M*A*S*H (notice story below).  His given name was Jameel Joseph Farah.  He wasn't originally planned as a main character of M*A*S*H, he just ended up that way.  He wrote his autobiography, Just Farr Fun.
The Craziness of Jamie Farr
I found this story in The Complete Book of M*A*S*H, so some people might know it already.
Once, Jamie Farr's agent was having trouble getting what he wanted in a contract.  So Jaime decided to take things into his own hands.  He got a gun from the prop department and went to the office of the negotiator, hiding behind trees and bushes on the way.  He went into the building, and kicked in the door of the office.  He held up the gun, and the person dived under his desk.  The two set up a meeting, and when Jamie came back, he brought flowers.  The contract with Jamie's conditions was formed.
