This 2009 'SNL' segment dedicated to house music made little sense but did provide an opportunity to see Madonna and Lady Gaga together for the first time.

After three minutes of silliness that included a Ryan Reynolds cameo, the ladies came out and began feuding. "What's wrong, Madonna? Can't get into the groove?," Gaga taunted, causing Madonna to pull Gaga's hair and choke her while asking, "What the hell is a disco stick?"

Ultimately, the skit was a chance for the two hitmakers to create peace by playfully mocking each other. Of course, after the way Madge dissed Gaga on stage every night during her last world tour, we doubt these two pop divas would appear together in a skit these days.
