I ran into a guy that told me the same joke 3 times today.. He was trying to get into a server room, I told him to check upstairs, as I was heading out. People pointed him to me, so he left me a note with that same joke, and a number to call (not knowing it was me). I called, and talked to him, letting him know that I had spoke to him in the garage, and let him know who to contact for what he needed, so he told me the joke again. Nice guy, just really wanted to make me laugh.

What has 4 legs and 1 arm?
