What was the first joke?

First joke:
Adam: “Better stand back, I don’t know how big this thing gets”

I remembered reading an article about how laughter originated awhile back. I found a less detailed version:

This might explain why we’re prone to crack up anytime we see someone slip and fall.

EDIT: Guess I should have included a link, huh? Well, here you go.

And Eve to Adam, “Is that it?”

Cheers for your suggestions, folks. I agree it would have had to be a visual gag, and I’m now inclined to think it was when Og stepped into a mammoth turd whilst the lads were out hunting.

Couldn’t find a cite online, but I remember from anthropology class that a really common ice age-era stone carving is a depiction of a monkey looking over his shoulder at a huge poop emerging from his butt, and sitting on the poop is a little bird looking back at him. At 10,000+ years old, it was described as the first identifiable joke.

What did the mastodon say to the sabre-toothed tiger?

Dude, you’ve got your tusks on inside out!

What did the sabre-toothed tiger say to the mastodon?

Nom nom nom.

What’s the difference between a woman and a club?

You can’t beat a club for hunting.

ETA: Thank you, I’m here all era. Try the gazelle! And don’t forget to drag your waitstaff round by the hair.

wouldn’t it have been about the travelling club salesman and the caveman’s daughter?

Is that an apple under your fig leaf or are you just happy to see me?

Thag: Look over there!
Bock: What there?
Thag: Hits Bock with stick.
Tribe: Ha ha ha.

Misfortune of others is funny, making misfortune for others is the joke. I’m sure the first joke was thrown shit.
