I was going to make a joke that Grandpa couldn't make it up the ladder -- and then I realized that after 12 years, I've never drawn a ladder into the pool.

I checked on many of the "dad jokes" that I've posted on reddit, and I discovered that I all the ones that I can probably illustrate. Well, there was one more.

After that, it would be borrowing other people's dad jokes. But, really, don't they belong to the world? Well, probably not. But a lot of Dads think alike.
