If you changed your last name, what would your last name be?

Awesomeness

...Or maybe just "Awesome"

Then everyone would call me "Mr. Awesome"

...Or change my full name to "Guess Who"

Then I could confuse callers every time I answer the phone:
{ Hello, Guess Who Speaking.
I don't know, who?
Guess Who.
Who? I told you I don't know.
And I told you twice that I'm Guess Who }
