4. Alex Kerkovich (Elisha Cuthbert) as Marilyn Monroe in Happy Endings
Episode: "Spooky Endings"
Air Date: 10/26/11
Marilyn Monroe is in the top five of Most Overused Female Costumes in both television and real life, but nobody, including us, cares about originality when beauties like Elisha Cuthbert are pairing blonde hair and a white dress. In "Spooky Endings," Alex decides to join the gang at a warehouse party in defiance of a sore throat that gives her man voice. Naturally, the guy hitting on her throughout the night turns out to be a gay guy who assumed she was a tranny because of the combo of her voice and costume choice.
