Individually Wrapped

A guy goes into a grocery store.

He sees a pile of potatoes, and asks the store keeper:

"What are those?"

"Those are potatoes"

"Can I have a kilo of potatoes individually wrapped?"

The store keeper shakes his head and starts wrapping potatoes.

"What are those?"

"Those are plums..."

"Can I have a kilo of plums all individually wrapped?"

The store keeper curses under his breath and starts packing plums.

"... and what are those?!”

"Isso são sementes de papoila e NÃO estão à venda!Those are poppy seeds and they are NOT for sale!"
