Casey Affleck portrays a bothersome Dunkin' Donuts customer in a new "Saturday Night Live" sketch that parodies the chain's commercials.

With a scruffy beard, a thick Boston accent and Bruins baseball hat, Affleck brings reality to a typical ad that starts with happy and cheerful "real" customers.

"I [expletive]' love Dunkin', what are you talkin' bout?" the actor says before he is seen smoking inside the store.

"Yeah, I come down to Dunkin' every day. Grab a cruller, have an extra large, three Parliaments, take a big dump, that's kind of the routine," he continues.

Things get messy after Affleck hits his friend below the belt, causing a mess inside the store. "How do you like the Vanilla Nut Taps?" he asked.

The skit ends after Affleck is made fun of by a passing customer after admitting that the best part of his day is when he is at Dunkin'. The 41-year-old then grabs his coffee and hurls it at the customer's car.

Affleck hosted "SNL" on Saturday along with musical guest Chance the Rapper. The episode was previewed by a comedic skit that featured the pair attempting to unsuccessfully decorate the Rockefeller Christmas tree.
