Sometimes I will see other players and laugh at their gamer tag, or admire how clever or unique it is.
For example, I saw a player called [b]A.Hydrogen.Atom[/b], which I thought was cool. The funniest one I saw recently was [b]Bilbo.Teabaggins[/b].
My own name, adamndirtyape, was taken from the original Planet of the Apes movie, where the hero is trying to escape the ape city but gets captured. He yells at them "Get your stinking paws off of me, you damn dirty apes!"
Hence my gaming tag, created when I used to play a ton of PvP. Taking down other players was like putting my paws on them so they couldn't escape. Eh, it's ok. But now I think not as clever as I thought, but it will do.
If you've seen gamertags you liked, or would like to explain your own let me know. I've always been curious about how people came up with their names. Cheers all ;)
