What happens to an 18 hour bra after 18 hours?

I don't know what happens to the 18 hour bra, but my bestest female friend in all the world, EVER , Jenny - sent me this postcard once and its
caption is:

'Odd incident with living bra' : and it had a picture of this woman shaving her legs sitting on the side of her bathtub and her bra had grown lips and was kissing her knee.
I still have it.
I have it attached with a magnet to my refrigerator.
My son gets it - my daughter is not quite at the age to understand.

what happens to my BOOBS at 18 hours...........

I don't know - what happens?

That presents an interesting mental picture.

It turns back into a pumpkin. duh.

They migrate south?

rug burns suck

speaking of rug burns - watch this video and listen to the lyrics in their entirety - I wish I could find subtitles.
This is my new favorite girl singer - I just hope she lives past thirty:

I hope she becomes an actress - I'd watch every single movie she'd make.

The bra only promises to keep you comfortable for 18 hours. After 19 hours the straps start to dig into your shoulders, your breasts start to sag and you may need medical treatment. Or so I am told.

Who told you that?
That's a little dramatic.
Actually, I think it means you can be comfortable in it for 18 hours, after which you take it off and are even more comfortable.
At least that's been my personal experiences with bras (although I rarely keep them on for 18 hours at a stretch)..
