Bieber takes punchlines on the chin

Justin Bieber tried to prove laughter is the best remedy when he took the heat at a Comedy Central roast on Monday night. It included host Kevin Hart, actor Will Ferrell as anchorman Ron Burgundy and comedian Dave Chapelle.

Here are some of the best lines about the 21-year-old pop singer:

• "I'm proud of you. You have it all. You literally are a guy who has it all - except for respect, love, friends, good parents, and a Grammy." - comedian-rapper Chris D'Elia
• "Justin Bieber wants to be black so bad, he's actually seen Kevin Hart's movies in theatres." - rapper Ludacris
• "Justin's fans are called Beliebers because it's politically incorrect to use the word retards." - comedian Natasha Legerro
• "This kid has spunk, moxie, and probably a few other STDs." - Ron Burgundy
• "Last year you were ranked the fifth-most hated person of all time. Kim Jong-un didn't even score that low, and he uses your music to torture people." - former basketball player Shaquille O'Neal
• "When you get to the county jail, hear me, you're gonna be the first dude who ever had a girlfriend and a boyfriend named Gomez." - rapper Snoop Dogg
• "Justin, you have no idea what you're in for. I'm sure it's great to have 60million followers on Twitter, but the only place people will be following you in jail is into the shower." - TV personality and ex-con Martha Stewart.
