[Alcahuete]

I know that the first video of Ellen saying a "magic" word only to have an unsuspecting audience member's skirt fly off has been posted before, but I recently found another video with what appears to be the same woman, same underwear, and same sort of gag. My question is does anyone know if this is a recurring gag? Are there maybe more clips of this joke that I haven't seen before?

The first attached vid is an edited version of the magic skirt off scene. The second is the new version, the action starts at around :49 seconds.
