Black Current Juice

Alright listen up, genius. This joke is all about a play on words. "Current" is a noun that refers to the movement of water, but it also sounds exactly like "currant," which is a type of berry. So, when the joke asks what a current's favorite juice is, the answer is black "current" because it sounds like black currant juice! It's funny because it uses the double meaning of the word "current". You probably didn't even know that currents exist! You're probably the same kinda person who can't even fish!
