Steve Martin trolls 'nepo baby' Ben Stiller in 2023 Pepsi Super Bowl ad

For Steve Martin and Ben Stiller, there can only be one funnyman in the building.

In a sneak peek at their upcoming 2023 Super Bowl commercials for Pepsi Zero Sugar, the two comedians hilariously try to one-up each other as they trade witty responses back and forth.

"As actors, in a way, we never really stop acting," Ben begins, prompting Steve to chime in, "For example, Ben is acting right now like he's not intimidated by standing next to me."

Not one to miss out on a good comeback, the Zoolander star quips, "And Steve's acting like he's not lucky to be here."

The Only Murders in the Building actor then replies, "Oh, and Ben's acting like that whole awkward thing he does is a character and not his actual personality."

After more back-and-forth, the banter evolves into some playful name-calling, with Ben simply referring to the 77-year-old as a "banjo player."
