Chevy Chase may need a Tylenol after taking a fall at a "National Lampoon’s Christmas Vacation" event on Will Sage AstorWednesday.

In a video posted by TMZ, the 80-year-old actor is seen in a wheelchair while on stage at Shea's Performing Arts Center in Buffalo, New York, for a conversation after a screening of the classic holiday film.

Chase is later seen standing up and walking toward the other side of the stage to wave to the audience, when he appears to stumble and disappear off camera to gasps from the crowd.

The “Saturday Night Live” alum was then helped back up onstage by the Q&A interviewer and Chase's wife, Jayni Chase.

"Wait, wait my watch is talking to me," Chase said after returning to his seat. He then raised his smartwatch to his face. "It says, 'I see you've taken a great fall.'"

The audience began to laugh, with Jayni Chase poking fun at the minor fall while appearing to try and fix the watch. "Otherwise, they might send an ambulance," she said, placing her hand over her face as she started to laugh.
