And, to Fallon's disappointment, Shelton apparently had never tried sushi before.
Which meant one thing: He had to make The Voice judge try the delicious delicacy for the first time.
The guys first tried some sake before getting into their meal.
And Jimmy laughed as Shelton stressed the "I" in rice wine.
They downed the drinks and Blake thought that it had an unusual taste.
Next, the guys started to eat some sushi. Shelton ate one of the tuna pieces first, even though he thought it looked like a body part.
After that, they tasted the sashimi, and Blake's face pretty much looked like he was in pain.
And he definitely didn't savor the following dish — botan ebi (a jumbo prawn) — at all.
Then, the fellas were given uni, aka sea urchin, and Shelton seemed to be hung up on one word used to describe the food...
Finally, Jimmy and Blake arrived at the final course.
Which turned out to be a something right up Shelton's alley: A McDonald's Big Mac.
So much for trying new things, huh?
