Joke 10: Why are the potatoes you bought green and full of buds?

I read the newspaper in the living room and my wife cooks in the kitchen.

Suddenly, my wife's voice came from the kitchen: Husband, go and buy some potatoes, remember, buy green and pollution-free!

I put down the newspaper and went out to buy potatoes. Half an hour later, I bought potatoes and gave them to my wife. I went back to the living room to read the newspaper.

At this moment, I heard my wife shout: Dear, why are the potatoes you bought green and full of buds?

I replied, don't you want green? I chose not only the green one, but also the one with long buds. I can break off the buds and use them as bean sprouts. Am I witty?

The wife growled, "What a genius!" Germinated potatoes are poisonous.
