A coworker who gets pregnant, and then for the next nine months you can't have a conversation with her that doesn't involve the fact that she is pregnant. Bonus for the ultrasounds pasted in her workspace, and the coworkers who fawn over the cuteness of said blob in In Utero.
Oh my god, I just just got back for my gyno, and look at these pictures!

What a self-entitled and failed actress with aspirations to be this century’s Princess Grace calls the future queen of England et al, who has forgotten more about clothes and style than ever was written in fashion magazines, when said fashionista pointed out flaws in her daughter’s flower-girl dress which the ham disagreed with. As reported by the mummer’s husband, whose DNA results are a State secret, in his expose that nobody but journalists will read and in doing so spat the dummy thereby proving he is the one who has one.

A man's scrotum.

The balls, particularly when it's chilly and they're tucked up tight against the body. The foldy skin looks like the brains of a tiny baby.

When a man cups his thumb and forefinger around the top of his testicles (up toward the choder aka taint). He then applies a gentle amount of pressure to make the testicles bulge. When you look at it just right- the "seam" that separates his left and right testicle makes his gonads look like a palm-sized brain. Hence the term "Baby (for small) Brains."
Tom: "Gosh Bob is really drunk."
Paul: "I know, I hope he doesn't take his pants off again."
Tom: "That guy gets fruiter the more he drinks."

Tom & Paul: "Ah, man not again. Put your pants back on homo, and grab us a beer."

When a man grabs his nut-sack, squeezes it from the base of his body, seperating the scrotum with a fist. The balls are in a "streched sack" state, which looks like the brains of a baby. Ball-hair accentuates this optical illution.
Hey look eveyone, baby's brains!!
