A blonde at the grocery store

A blonde at the grocery store:
- I would like 4 tomatoes, 4 potatoes and 4 onions
- I can help you with the tomatoes and the potatoes, but not with the
onions…
- Ok… than I’ll have 2 tomatoes, 2 potatoes and 2 onions
- I see you don’t understand me: I have tomatoes, I have potatoes, but I
have no onions
- I see… than I’ll have a tomato, a potato and an onion
- Ok, let’s do this the other way around. If you take the “mato” out of the
“tomato”, what do you have?
- Aaaa… “to”?
- Right, and if you take the “tato” out of the “potato”, what do you have?
- Aaaa… “po”?
- Excellent, and if you take the “fuck” out of the “onion”, what do you
have?
- Aaaa… aaa… but there is no “fuck” in “onion”
- Exactly, there is no fuckin’ onion!
