Efron, 26, had no trouble keeping up onstage with his That Awkward Moment costars Michael B. Jordan and Miles Teller, with whom he presented the best comedic movie award.
"So, the three of us know just a little bit about awkward moments," Efron said. "In fact, there was this one time that I texted a girl and she didn't text me back for 20 minutes."
"What's awkward about that," Teller wondered, before quipping: "Twenty minutes is an average reply time when you're talking with me."
Efron seems to have fully recovered from his broken jaw, the result of slipping on a puddle at his home in Los Angeles. The injury required the Parkland star to have his mouth wired shut.
The fall was another setback for Efron, who completed a rehab program in the spring of 2013.
