Do I look like Michael Jackson to yooooou?
I'm sorry Janet, I thought you were your brother for a second. :P
Here's a classic:
Flexan: Cover me, I'm going in!
PowerMad9: mmph... that's what the p*nis said to the condom...
And another:
Sniper: WOAH! Where'd you come from?
PowerMad9: Well, when a man and a woman love eachother...
And, my favorite:
*Sniper kills me in game*
PowerMad9: Omg... You assh*le...
Sniper: Hey, without us assh*les, you sh*theads would be out of business.
