Not even the fittest among us are safe from the ravages of time.

Jake Gyllenhaal appeared on Late Night with Seth Meyers last night to promote his boxing pic Southpaw (which required him to get in now- legendary physical shape). But before he made it onstage, Meyers surprised him in his dressing room — and got way more than he bargained for.

The segment began when Meyers discovered that Gyllenhaal had left his phone on the guest chair on stage and decided to take it backstage to return it. The camera followed him to Gyllenhaal's dressing room, where he knocked on the door, saying, "Hey, Jake. Forgot your phone, Buddy!"

But when Meyers opened the door, things got awkward as he discovered a bald Gyllenhaal (with just a few remaining hairs hanging onto his sad comb-over) sitting at his dressing table, poised to put on a toupée.

After a long, hilariously melancholy gaze at one another, Meyer just closed the door, looking as if he might never fully recover from the encounter, and softly said, "We'll be back with more Late Night."
