Barkeep on "The Simpsons"

MOE

The surly owner of Springfield’s tavern is known for his signature catchphrase and unibrow.

This clue refers to Moe Szyslak, the grumpy but lovable bartender who runs Moe’s Tavern in the animated show The Simpsons. The name "Moe" is short for Maurice, but he’s almost always called just Moe on the show. If you’re a fan, you’d recognize him by his raspy voice, his signature green shirt, and his endless supply of Duff Beer. The answer is simply his first name, spelled as "MOE."
