John Stamos’ family singalong went wrong -- in the best possible way.

The " Full House" actor gathered up wife Caitlin McHugh Stamos and their almost 2-year-old son, William "Billy" Christopher Stamos, to sing a rendition of the iconic Disney song "It’s a Small World (After All)" in their big, luxurious bed.

Billy, as it turned out, had other plans.

The trio begin the video sitting in the bed together, with John Stamos, 56, playing a guitar and Caitlin McHugh Stamos, 33, strumming a ukulele while they both wear Minnie Mouse ears. While they’re trying to enjoy a social distancing jam session, their little guy adorably keeps interrupting them.

In the video’s caption, the "ER" alum -- who throws a Mickey Mouse doll at the camera in the final seconds -- called the attempt a "small disaster" while reminding followers to stay at home amid to help keep the coronavirus pandemic in check.

Fans of this celebrity brood won’t be surprised by their love for Disney. After all, they got engaged at Disneyland and honeymooned at Walt Disney World.
