Help me choose my new gamertag, plex!

Ok so I'm tired of my current gamertag. So I got some points, bought the new map pack for MW2 and now I have 900 points remaining but I don't know what to spend it on. So I decided to change my gamertag... but now, I don't know what to change it to. So help me choose plex. Here's a few:

Homer Pimpson or Bart Pimpson
Guck Fe Mently (if you think a little you'll understand)
I Killed Kenny or iKilledKenny
Osama Bin Laden
Hugh Janus
Blue Waffle or A Blue Waffle
