Basically I post a picture, I then wait about 5 - 10 comments later and pick who has the funniest comment... then they post a picture.
NOTE: I am going to post a comment after my picture, just to show how it works... no one else should do this:
"That is one hell of a big zit... oooooh aaaaaah...
Got it!"
Knock yourself out guys.
