'Punk'd' trailer: Dianna Agron, Khloe Kardashian Odom, Zac Efron are easy marks

Nearly a decade might have passed, but the new full-length trailer for MTV's reboot of "Punk'd" proves that embarrassing celebrities on camera is just as hilarious the second time around.

Instead of a trucker hat-clad Ashton Kutcher, this time the pranks are engineered by a different celebrity every week. Troublemakers include Justin Bieber, Miley Cyrus, Bam Margera, Hayden Panettiere and Heather Morris, while the unsuspecting marks include Taylor Swift, Liam Hemsworth, Tyler the Creator, Zac Efron and Dianna Agron, among others.

Does it make us juvenile if we laughed the hardest at Khloe Kardashian Odom trying to help out a man who zips, um, himself into his pants a la "There's Something About Mary"? Something about her earnestly telling him "You need to lay down or you might lose your testicles!" was so hilarious...

"Punk'd" premieres Thursday, March 29 on MTV.
