A man walks into a diner to order breakfast. He gets seated, and goes down to sit at his assigned table. He picks up his menu to read it,and decides he wants to order the eggs Benedict and some lemonade.
He waits,and eventually after a short while,his waitress shows up,introduces herself and asks him if he's ready to order some drinks or any biscuits,before he orders his meal. He says "no thank you on the biscuits,but I'll have some lemonade,please. And a glass of water too,thank you!"
"The waitress says okay sir,no problem I'll get right on that for you. No on the biscuits,with lemonade and a glass of water. Alright!"
The man says "wait,before you go,i must ask you a strange question! What domain to humans belong to in taxonomy?"
The waitress replies "eukaryotes?"
The man says "No, I don't carry any grains on me, sorry!"
