Madonna and Lady Gaga in REAL LIFE Dance Off

Just when you thought you couldn't possibly hate Madonna and Lady Gaga any more than you do right now, they go and do something like this:

Madonna and Lady Gaga continued their catfight from 'Saturday Night Live' well into Sunday — they got into a one-on-one dance-off at SoHo hot spot Submercer at a Sunday night birthday party for Madge's manager. '[The DJ was] alternating their songs ‘Holiday' and ‘Poker Face,' and then they both started going at it,' says an onlooker. 'Madonna seemed to be the winner. People were going wild.'

There's not any video of the real dance-off, but just imagine two shemales in S&M attire vogue-ing and thrusting like they've got tardive dyskinesia and you've pretty much covered it. It's like my Dad always said — 'it's not really a birthday party unless a tranny pulls a groin muscle.' Of course, 'until a little kid throws up from crying so hard' seemed to suffice until I went away to college. Asshole.

Lady Gaga looking more beautiful than she ever looked in her life this past summer:
