It's an unwritten rule that dads have to embarrass you growing up - otherwise they're just not doing their job properly.
Redditors have now shared their best 'one time my dad' stories and they're utterly brilliant.
From the dad who opened a bag of sugar like a packet of Doritos on the sofa (you know how this ends...) to the dad who made a song about penises and vaginas to teach his kid to love their body, here's the best of the bunch...
The One With The Dog
"One time my dad's fart smelled so bad my dog threw up."
The One With The Potato Cannon
"One time, my dad and I built a potato cannon. We proceeded to launch potatoes into orbit from the backyard... Until we heard a car alarm go off on the next street, somewhere in the general direction of where we launched the potato."
