Lady Gaga, you have arrived. Like Beyonce’s “Single Ladies,” Gaga’s “Poker Face” has become so wildly popular that even Christopher Walken has jumped on board covering it. This tribute does make us feel slightly uncomfortable and we hope Walken sticks to acting. But admit it, when Gaga busts out this song in the club, you can’t help but dance. After the jump, a few more amazing odes.
