Chevy Chase remained in good spirits despite a slight setback Wednesday.

The 80-year-old comedian stumbled off the stage before a screening of his classic film, "National Lampoon's Christmas Vacation."

Chase used a wheelchair on the set at Shea's Performing Arts Center in Buffalo, New York, and fell off the stage shortly after standing up. A video shared by a TikTok user documented his fall.

"He took a fall at the part of the stage that was not lit well, but thanks to all his falls on ‘SNL’ it was like riding a bike again," his representative confirmed in a statement shared with Fox News Digital. 

"Just a little boo-boo. All good."
