FBI's Target

Alright, listen up, you smooth-brained ape. First off, your name is "W Rizzler", so I can already tell you have zero rizz. Now, the joke is playing on the idea of someone being so desirable that even the FBI is after their, uh, "package." It uses an absurd situation to imply that the person is so hot they need to hide their, ahem, manhood, inside another person to keep it safe. It's not sophisticated humor, but it is what it is.
