I was sitting on a bench at work one day. A man came over and sat down beside me. He reached over to my leg and asked,"Hey there guy, you don't mind if I do this, do you?", as he started to rub my knee...
"Just messing with ya!", he said, "My name is Jared...most people would have freaked out...you must be pretty cool."
"Sure man, I knew you were messing!"
Easiest friend I ever made! :D
