The Vampire Diaries cast has filmed more than 100 episodes together, which means there has been plenty of opportunity for the most important of on-set activities: pranking! Kat Graham (Bonnie Bennett) talked to Just Jared about the scariest prank ever, courtesy of co-star Ian Somerhalder (Damon Salvatore). What prank did Ian pull on Kat?

“I get pranked a lot,” Kat confessed. “There’s a lot of dancing going on in the hallways. Ian Somerhalder can cut a rug. But, I’m usually getting scared. Somebody popping out of somewhere.” We love that the TVDers are literally dancing on set. Talk about a positive work environment! But we’re not sure how prank-y we find impromptu dancing. What did Kat call the “most memorable prank” ever pulled on her?

“We were actually driving from set, at the end of the street, and I had my window rolled down,” Kat recounted. “Then all of a sudden, somebody goes into my driver’s side window and goes, ‘WaAaAAAaAAaaa.’ And it’s Ian just jumping out of his car in the middle of the night, scaring the crap out of me.” Ha! Out-of-context pranks are always the scariest, and we love that Ian just went for it. Though, it’s hard to imagine the gorgeous actor ever being an unwelcome sight.

What do you think of Ian’s prank? Would you have been scared? Sound off in the contents below!

The Vampire Diaries airs on Thursdays at 8 p.m. on The CW.
