Watch Fallon, Dwayne Johnson as Awkward 'Ermahgerd Prom Guys'

Actor ate candy (Pop Rocks!) for the first time since 1989 on 'Tonight Show'

Jimmy Fallon and Dwayne Johnson played nervous, awkward "Ermahgerd Prom Guys" on 'The Tonight Show.'

Jimmy Fallon and Dwayne "The Rock" Johnson became bumbling senior prom outcasts on Thursday's Tonight Show. "Ermahgerd!" they giggled anxiously working up courage to ask girls to dance. 

"Nice corsage," Fallon tells his bro, scoping out the dance floor. "Thanks!" Johnson responds, in a braces-induced lisp. "My mom helped me put it on because I was piercing my nipple." After hyping up each other by declaring they "totally scro-tally" rule the school, they ruin the vibe with each nervous female encounter. 

Fallon tells one girl, "If you chew the chips lerng energh, they terst like mashed potatoes." Moments later, Johnson yells out "berner alert" after a potential companion asks him to slow dance. Realizing their fate for the evening, the friends unite for some coordinated solo dancing and pose together for a "Prerm 2016" photo.

Johnson, promoting his new comedy, Central Intelligence, got a special treat during his sit-down interview with Fallon. The host grilled the actor about a weird personal factoid: that the hadn't eaten candy since 1989. Fallon tempted Johnson with Twizzlers, Nerds Rope, Ring Pops and a massive gummy worm. After some requisite phallic jokes, the host poured Pop Rocks into his guest's mouth. "So this is what candy tastes like!" Johnson exclaimed.
