Is it a movie trailer or an advertisement for Lady Gaga’s new album, ARTPOP? Because there sure is a lot of Gaga in this one — not to mention it features an unheard track off the upcoming album called “Aura.” Otherwise, you’ve got your pick from a buffet of stars: Mel Gibson’s evil laughter, Michelle Rodriguez’s eye patch, Charlie Sheen (billed as “Carlos Estevez”) with the president’s red phone, and Danny Trejo with (surprise!) a machete.
