As we all know, Zac Efron is something of an accomplished bra unhooker with his masterful technique the “pinch and slide.” What I didn’t know is that Jimmy Kimmel is also skilled at the art and decided to challenge “The Lucky One” actor to a bra-unhooking duel on his show last night.

Standing in for the female forms were Guillermo 1 and Guillermo 2, each wearing four identical bras that Kimmel and Efron raced to unhook. As soon as the gun sounded, it looked like Kimmel had it. He was calm and patient while Efron fumbled with both hands. But it was the last one that caught up to Kimmel and Efron managed to take the Crown.

Zac Efron has created an easy one-two step system for hopeless guys who want to unhook a woman’s bra. It’s called the pinch and slide. The Lucky One actor was asked by Mel and Matty from Hot 30 Countdown how quickly he can pass their “bra test.”

Mel, whose boyfriend is apparently a bra fumbler (TMI), didn’t believe any guy could unhook a woman’s bra in one go. Conveniently, the Sydney reporter whipped out a spare bra from her bag so Zac could conduct a spontaneous de-robing lesson.

Zac even taught the unskilled Matty to unhook it in one go, though it took a lot of effort and concentration. Not everyone can be as suave as Efron.
