Singer Justin Bieber is quite a prankster. He recently went undercover as a tour guide on the set of the popular sitcom “Friends” in California.
Some of the fans of “Friends” didn”t suspect him as he wore a pair of glasses and comical facial hair. At one point, he called himself a “Joey guy” and reenacted one of the Matt Le Blanc character”s catchphrases, “How you doin”?”
“I gotta be honest, I”m Justin Bieber and I”m just messing with you guys. This is all a set up,” he says to one couple before posing for a selfie with the shocked fans, reports people.com.
