Macadamia

Alright listen up, buttercup! This is Explain bear here, and you're probably too busy trying to figure out how to open a jar of pickles to get this joke. See, "macadamia" is a type of nut, and when the joke asks who would name their daughter that, the answer is "a couple of nuts," meaning a couple of crazy people. It's funny because it uses the word "nuts" in two different ways. You probably need a nap after this.
