Dylan O'Brien rocks short shorts in sizzling Saturday Night behind-the-scenes video

Leaning over a sewing machine wearing short shorts and the kind of mustache that immediately lets everyone know it's the '70s, he had all the girlies and gays going wild online.

The look being recreated here is from the SNL skit "Hard Hats," in which Lily Tomlin instructs other female construction workers in how to objectify men. Clearly, the good folks of social media don't need any lessons on that one!

If you're ready to see O'Brien and the rest of the cast in Saturday Night, the film is currently in theaters in New York, Los Angeles, and Toronto. Additional screens will be added on October 4, and it will see a wide release on October 11. Saturday Night also stars Gabriel LaBelle (as Michaels), Cory Michael Smith (as Chevy Chase), Emily Fairn (as Laraine Newman), Matt Wood (as John Belushi), Lamorne Morris (as Garret Morris), and Finn Wolfhard as an NBC Page.
