The Alien Parasite Hypothesis, 1 song

Amy finds she has sexual feelings for Penny's ex, while Koothrappali and Wolowitz try to prove who would be the better superhero.

  • Attitude Strut — Nick Evans Mowery
    This song is playing as Amy, Bernadette and Penny are spending their night out at a bar. Amy let’s out an involuntary “Hoo!” a couple of times, including when Zack bends over to pick up a box.
