It’s never a dull moment when Blake Shelton visits his old friend and late-night talk show host Jimmy Fallon. The “Came Here to Forget” singer returned to the Late Show With Jimmy Fallon Monday night (Oct. 10) for a little payback. If you remember, back in May 2016, Blake visited Jimmy and was made to try sushi for the first time.

Well, this time it was Jimmy’s turn to learn something new. The late-night host stepped out of his comfort zone to try his hand at milking a cow.

“I’m here with my pal Blake Shelton,” Jimmy says in the clip. “We’re at Riverdale Stables here in New York. Now Blake, the last time you were on the show, I made you do something you’ve never done before—try sushi.

“Yes, I’m still having nightmares about that,” Blake replied.

“Being the nice guy that I am, I thought I’d give you a chance for some payback,” adds Jimmy. “You’re going to make me do something I’ve never done before—milk a cow.”

That’s when the hilarity ensues. Blake introduces Jimmy, who is dressed like—as Blake says, “Woody from Toy Story,” to a cow named Oreo. Blake then proceeds to instruct Jimmy how to milk a cow. In the end, Blake gets his revenge by making Jimmy chug the warm milk straight out of the cow’s teat as Blake throws the milk over his shoulder. All in good fun.

Watch Jimmy and Blake go through the process of milking a cow. We dare you not to laugh.
