William shared this clip of the exact moment both his wife and daughter took a tumble.

''We were teaching our daughter to ride a bike,'' he told WooGlobe.

''She got fed up with my style of teaching, so she asked if her mother could help her.''

The switch sounded wise until balance betrayed her mom.

''My wife doesn't have good balance due to hearing loss and ends up tripping,'' he added.

Mom was down, dad was filming, and gravity was working overtime.

The girl rolled forward and ended up nearly decapitating her mom on the way down.
