Who's grumpier — Roy Kent or Oscar the Grouch? 

That question was answered on Thursday's episode of Sesame Street, which featured Ted Lasso star Brett Goldstein facing off with another lovable crab with iconic brows.

When Goldstein — a known Muppet superfan — runs into the furry, green, garbage-loving grump, he asks him if he'd like to play checkers. Oscar makes it clear he's not interested, holding up a familiar-looking sign that says "Scram." After the two growl and grunt at one another, furrowing their thick eyebrows, Oscar asks: "Can you read? It says, 'Scram'!" Goldstein definitely knows how to get his grouch on, but he's no match for Oscar. "No, I get it," says the actor and comedian before walking away.
