Danny DeVito continued his streak of being pretty damned amazing this weekend when he hit up New York City's swanky Spotted Pig restaurant on Friday night (March 29) with his 'It's Always Sunny in Philadelphia' co-stars ... and then went to work in the kitchen.

The New York Post reports that DeVito -- who recently reconciled with wife Rhea Perlman and reaffirmed our belief in everything good and holy and adorable -- simply moseyed on over and asked the eatery staff if he could pitch in.

“He just wandered in and asked if he could help,” a witness said. “He was entertaining all of the customers on the first floor of the restaurant and the cooks.”

DeVito then posed for photos with the staff because, well, he's Danny DeVito, and he's awesome. Here's hoping he earned some good tips.
