Josh Duhamel may be known for many things, but checking people out at a grocery store isn’t one of them... Until now. He recently did an ad for Diet Pepsi, and his antics on the screen were surprising to many of his customers.

In addition to the surprise of having Josh scan their groceries, they watched on as he drank from their soda bottles, popped out from the middle of displays, threw fruit on the floor, and raced junior shoppers around the store.

Duhamel and his wife Fergie are expecting a baby boy in September or October, and the actor will be seen in the upcoming film Scenic Route, which hits theaters August 23.
