On the prank scale from "there's something on your shirt" to 10, maliciously cropping someone out of Instagram pictures is probably a 3. But still, Chris Pratt has been needling his Passengers co-star Jennifer Lawrence by posting pictures of the side of her face or the back of her head or one of her hands to his Instagram.

Chris, you little scamp you!

When JLaw stopped by Jimmy Kimmel Live Monday night, and had this indecency thrown into her face by the host, she decided not to take it lying down. If Pratt was going to cut her out of Instagram photos, she was going to ... spray paint his face on a Passengers ad on a bus. Making it all the way up to 4 on the prank scale.

What will these crazy kids think of next!
