What did the girl mushroom say about the boy mushroom after their first date? ?

She said that he was a fun gi. This is a pun because fungi is a mushroom and here it is a play on words because of "fun guy" sounding the same as "fun gi". Since they are both mushrooms, the joke stands and these types of puns are very common among people because of their simplicity.
