They sound like crafted jokes. Here's one from a book about the Yankees.
Yogi and his mates were walking in downtown N.Y. when at a cornor, a guy carrying a baby grandfather clock walked into him. Yogi replied, "why don't you use a wristwatch like everyone else?".....lol


I'm waiting for Club_Goer. He knows more Yogi-ism's than Yogi.
