A monkey enters a bar and orders a coke.
The bartender, surprised by the fact that there is a monkey in his bar, gives the coke and thinks:
it’s just a monkey!
He doesn’t understand money!
So he asks a really high price.
Once the monkey has paid, he talks with the monkey for a bit.
“There’s very few monkey at this bar.”
The bartender says.
“No wonder!”
The monkey replies.
“Just a coke is prohibitively expensive!”
