Watch Zac Efron Get Punked On The Set Of High School Musical 3

Apparently Ashton Kutcher is not the only prankster in Hollywood.

In fact, we hear that Zac Efron has been such a prankster on the set of his new movie "High School Musical 3 - Senior Year", that his fellow cast mates decided to gang up on Efron and settle the score once and for all.

It appears that Efron has been abusing his power with water balloons throughout the entire production of HSM 3, and fellow actors Vanessa Anne Hudgens, Ashley Tisdale, Lucas Grabeel and Corbin Bleu decided to get even - and they got it all on video!

Of course they had to realize the video would make it to YouTube and InfoStar, but we suspect that was all part of the plan.

The revengeful cast staged an elaborate covert attack with water cannons and buckets, and strung out over 100 rolls of toilet paper in Efron's on-set trailer.

The video below catches the entire stunt on tape. Enjoy.
