(I have been helping a customer find an apple tree he wants to give as a gift.)

Me: “Just so you’re aware, if the person you’re buying this for doesn’t have another apple tree, or there isn’t one close by, this tree isn’t going to produce any fruit.”

Customer: “What do you mean?”

Me: “Well, apple trees only produce fruit through cross-pollination.”

Customer: “What does that mean?”

Me: “Well, the simplest way for me to explain is: People are unable to reproduce with themselves, right?”

Customer: “So, is this tree male or female?”

Me: “Well, apple trees are asexual.”

Customer: “So, it’s gay?!”
