Ellen DeGeneres is one of the greatest pranksters of all time and her latest prank was pulled on unsuspecting Chicago Cubs fans.

Ellen sent Adam, one of her writers, to go undercover as a cashier at Wrigley Field.

He was stationed inside the gift shop and the rest is history!

Honestly Ellen, how do you do it!?

I laughed so hard watching this video. I'm so thankful for how patient each of the guests shopping in the store were with Adam. It's easy to get your blood boiling when things don't go your way.

What a hilarious prank!
