DUI's should always be taken seriously.

But in joking about his recent arrest, John Stamos reminded the audience on the set of Fuller House why he's been a fan favorite for so many years.

Stamos made his first appearance on the show's set Tuesday, after spending 30 days in rehab for his June arrest. The actor, who plays Uncle Jesse on the family sitcom, left the crowd in stitches when he made light of his bust after a prop car failed to arrive onset.

"Well, I have a car," Stamos said while explaining to the group why they couldn't shoot the scene. "But I can't drive."

Beside the impromptu comment, a source told TMZ Stamos "nailed every scene."

Stamos has been giving fans a laugh by posting photos from behind the scenes along with Full House co-stars Lori Loughlin, Bob Saget and David Allen Collier.
