A lawyer, a carpenter and an astronaut were having drinks in a bar when suddenly one gets up and hits the other. "who hit me?" "It wasn't me." "I didn't see too much either." "It must have been the dog" "What dog?" "I'm blind so I couldn't see a dog." "Doh, that means I hit myself." "hahahahaha how strange I thought you guys had hit me. Sorry about that."
