Why can't all pranks be like this?

In honor of the new Tonight Dough ice cream, Jimmy Fallon decided to give out free samples and surprise customers at the Ben & Jerry's scoop shop. In order to pull it off, "The Tonight Show" set up a "state-of-the-art ice cream feeding machine," aka a robot arm holding a spoon, which fans didn't know was being operated by Fallon.

All the proceeds of Tonight Dough go to the SeriousFun Children’s Network, and if that isn't enough excuse for Fallon to fling ice cream on unsuspecting people, what is?

"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET on NBC.
