Two weeks ago, in the first Stand-Up Showdown, Greg Giraldo's "Brokeback Mountain" was voted funnier than Louis C.K.'s "Gay Marriage" bit.

Then last week, 75% of voters still favored Greg's clip as the funnier bit over Christopher  Titus' "Fell Into a Bonfire".

So now we put Greg's bit up against Lewis Black's "Airplane Travel" clip and once again you decide which is funnier.

The winner, of course, will then be matched up with another comedian's stand-up clip, and on and on.
