Bruce Willis Ends Daughter Date Night With Classic Fart Joke

Bruce Willis had a lovely evening with his three daughters, but the night turned sour when one of the girls decided to make the star the butt of a fart joke.

The "Die Hard" star went to dinner on Wednesday with his eldest girls — Tallulah, Scout andRumer — on the eve of Rumer's 30th birthday. The foursome seemed to be enjoying their night, stopping to take a sweet family photo when Bruce dropped a classic elementary knee-slapper.

"Just before we took this photo my dad said, 'hurry up, I have to fart,'" Scout captioned the photo, ratting out her pop.

And based on the photos, it looks like she could be telling the truth.

Bruce's face seems to show he's about to let a big one rip.
