Pete Davidson returns for John Mulaney's latest musical, alongside Andy Samberg's Singing Bear

Another famous face from “Saturday Night Live”s past stopped by to celebrate the show's groundbreaking 50th season.

Former cast member Pete Davidson made a cameo appearance this week SNLalong with Andrew Dismukes as a customer at the Port Authority Duane Reade, run by John Mulaney's cashier. It became one of Mulaney's signature musical parodies, a la “Diner Lobster,” when Davidson asked if he could buy a jug of milk from the store's mini-fridge. The cashier couldn't believe he wanted to buy milk from “the fridge that's hotter than the rest of the store.”

Then the cashier turned to singing possums, played by Kenan Thompson and Ego Nwodim The Lion King-Style about how milk comes from…well, a possum's teat. (But it's high in protein!) Marcello Hernández played a bottle of shampoo kept under lock and key to ward off shoplifters, and Bowen Yang played a creepy bus driver who makes toilet gin in the bus restroom. Additionally, Chloe Fineman led a group of Timothée Chalamet impersonators who invaded the Big Apple by bus.

However, stealing the spotlight was SNL Alum Andy Samberg appears as the dead bear that Robert F. Kennedy Jr. was forced to leave behind in Central Park years ago. Samberg broke out a Hamilton-style rap about the man who dropped him off there: “With a worm on his brain/Is that what drove him crazy?”
