I think it would be funny to change my name to Mike Oxlong. I can imagine the hilarity which would ensue (say the name out loud if you need to).

Someone: "Mike Oxlong?"
Me: "It is? Wow, maybe you should go into porn!"

Someone: "Is Mike Oxlong here?"
Me: "It may be, but I don't have a ruler and I don't want to see it"

Somone: "Hello, Mike Oxlong?"
Me: "Well, you sure like to brag, don't ya?"

etc...

Also fond of Jack Mehoff... hmmmm
