Turns out, John Krasinski is really, really good at pranks. Just ask Jimmy Kimmel.
"Ho! Ho! Ho!" said a half-naked Santa dangling from Jimmy Kimmel's window on "Jimmy Kimmel Live!"
"What? Oh my God!" said Kimmel.
Krasinski and Kimmel have beenpranking each other around the holidays for a while now, and this year, it was Kimmel's turn to prank Krasinski. But the actor decided he didn't want to wait to be challenged.
"I see what's gonna happen here," said Kimmel.
"Do you? Yeah!" said Kransiski.
After Krasinski pulled off three solid pranks, Kimmel decided to step things up a notch. He made posters for a yard sale with Krasinski's face and real-life address on them and left them up all over town. Now, that's intense.
And if that wasn't enough ...
So take note: You do not want to be on the wrong side of a Jimmy Kimmel prank war.
