Question: Why'd the chicken cross the road? Answer: To get to the other side. Hahahah-wait. That's... Not funny. That's not even a joke, and yet it's usually referred to as a joke.
Okay, then... One of the most universally recognized "jokes" isn't even a joke. Of course you cross the road to get to the other side! And before you say, "It's a joke because the chicken is dead and he's crossing the road to THE other side. To the afterlife.", let me say something. I'm pretty sure that's not the other side the "joke" is referring to. I'm pretty sure the "joke" is being literal. This "joke" also has some spin-offs, such as...
"Why'd the turkey cross the road?"
The answer? "Because it was the chicken's day off."
*sigh* THAT'S EVEN LESS FUNNY THAN ITS PREDECESSOR (which isn't to say its predecessor was even funny; it wasn't)!
Okay, THIS is a joke.
"What do you call a crazy dairy farm?" "UDDER chaos!" That is a joke.
