When your grandson is best known for pulling pranks, it's probably best to never, ever trust him. This grandmother probably realizes that now.

Roman Atwood is famous for pulling pranks, like turning his house into a giant ball pit. For his latest prank, he decided to have a little fun with his grandmother, by 'blowing up' her car.

What Atwood's grandmother didn't know was that he wasn't actually blowing up her car, but another car that looked exactly like hers.

And, if that wasn't enough, Atwood also surprised his grandmother with a brand new car, once the whole thing was said and done!

It turns out having a grandson that's a world famous prankster isn't the worst thing in the world.
