The Bay City Rollers were on to something, because we're ridiculously excited for this weekend's episode of Saturday Night Live!!
If you wondering why host Zach Galifianakis looks so sad in the teaser, it's because Jason Sudeikis didn't notice Justin Bieber's freshly painted portrait on the big guy's nails!!!
Ch-ch-check out the Hangover III stars' HIGHlarious hijinks in the NBC promos (above)!
Holy guacamole, Zach just flashed J-man his tiny pants pirate!! Yikes!!
Catch more of their beautiful bromance this weekend along with musical guests Of Monsters and Men!
