All the Ridiculous Things That Make Pitch Perfect 2 Irresistible

We got a peek at this riff-off in an early clip, but seeing it unfold in its entirety was amazing. Everything about it is ridiculous: David Cross as a mysterious a cappella enthusiast, categories about butts, and the cameo from the Green Bay Packers. Shout-out to fellow cameo-maker Keegan-Michael Key. Both of these funny guys made the most of their short time on screen, and they're just as memorable as the rest of the cast.
