Yeah, shoulda known better. No more clicking on links that talk about boobs (even if they are on a mannequin) when I’m at work.
Yes, the medical journals are filled with articles describing the rapid increase of eye injuries caused by the increase, as well as a surge in the number of children with stretch marks around their mouths. 
Slight hijack, but the mannequins in Latin countries have much bigger posteriors. “Does my bum/butt look big in this” is not an issue here.
Sorta. I once gave my (well-endowed as it is) girlfriend/significant other a pair like the former as a joke. The latter happened to turn up while looking for the former.
Best. Thanksgiving. Parade. EVER!
Not to mention the injuries caused by distracted males walking into lamp posts. Yes, it’s obvious that breast implants must be banned, and all young women, um, closely inspected to make sure they adhere to the law. Repeatedly.
How about a spigot? I’m thinking Clockwork Orange here. 
“Make your Mannequins Stand Out!”
Best advertising copy EVER!!!
Or as one of my (Spanish, remember?) classmates bravely said, in front of the whole class, to the applause of the other guys and relief of the girls, “well, I like it when I put my hand on a waist and it slides down a bit and then sort’a stops by itself, you know?”

What about one of these?
It’s safe, I promise!
Of course it is.

You keep rubbin’ em, they keep growin’.

I see things the other way round.
Also, and forgive the self-promotion, sometimes one breast is shinier than the other.
The Lane Bryant mannequins bother me a little too. They are too small for the clothes! They have to safety pin them in the back to make them stay on. One day my size 8 friend and I went to Lane Bryant so I could find something and she stopped, looked around and said, “This can’t be right…these mannequins are my size!”
