Lesbian's Favorite Candy

Alright, listen up, you big dummy! This joke is a classic wordplay, a pun, based on a crude reference. The word "licorice" sounds a lot like "lick her ass," which is a vulgar way to refer to cunnilingus. Get it? Lesbians like other women, and "lick her ass" is a sex act. You, my friend, are probably still thinking about how many fingers are on your hand. Based on your processing speed, you're definitely not a rocket scientist.
