They say death and taxes are the only certainties in life. They may want to add "dad jokes" to that list.

Yes, dads are notorious for telling lame jokes, the kind that make you want to hide under the table when he thinks he's being funny with the waiter or jump into the nearest oncoming car when you bring a friend home from school.

It's just one of those things. Welll, Nickelodeon Australia has put out this very funny video called "Dad Joke Survivors," in which kids relay some of the awful jokes their dads have told them. They're the kind of jokes that can scar children for life -- or at least until the boys become dads and find themselves following in their parents' footsteps.

Some of the jokes are just terrible, but, you know what? Delivery matters, so some of these could be better if they're said properly. We especially think the joke about constipation gets a bum wrap. That's pretty clever.

What say you? What's the worst dad joke you've ever heard?
