VIDEO: Watch Courteney Cox Quiz 'Friends' Superfan Charlie Puth on the Series

On Billboard's Quizzed, Courtney Cox puts Charlie Puth through the ringer to see if he can earn the title of the ultimate Friends fan.

Puth begins by putting his foot in his mouth and saying, "It's so funny, the way you speak, you hit the same pitch that Monica does." Cox dryly replies, "Oh great. I wasn't acting, you mean?"

Courtney Cox begins with the first round: True or False. Cox alleviates his nervousness by saying, "If it makes you feel any better, I don't know one of the answers." This must be a really tough quiz!

One of the questions was: "Monica's biggest pet peeve is people who chew with their mouth open. True or false?" Puth says "false," claiming that Monica's biggest pet peeve is people not cleaning up. But actually, the answer was: animals dressed as humans.

Round Two was General Trivia. A highlight questions was: "What book did Joey keep in the freezer because it scares him?" The answer: "The Shining."

Another stellar moment: "What does Joey do to get back at Chandler for hiding all of his clothes?" The correct answer: "He wears all of his clothes."

Round Three was quotes and one of the best was: "You can't just give up. Is that what a dinosaur would do?" Puth gets stumped for a second, thinking Monica said it but it was actually Joey.

Puth wins the Geller cup, which Courtney Cox admits she has had by her bed since the show wrapped and Puth starts crying.

According to billboard, they wrap up Quizzed with Puth singing "I'll Be There For You" and the whole thing is just so hilarious and awesome. Watch the full clip below.
