Excuse Me, You're in My Son

Alright listen up, chucklenut. This "joke" is playing on the double meaning of the word "son." On the surface, it sounds like the woman is telling Michael Jackson that he is standing on her child at the beach, which is rude. However, it is also implying the allegations against Michael Jackson, suggesting he's "in" her son in a more nefarious way, if you catch my drift. You probably don't, smoothbrain.
