Did anyone's Grandma's tits ever get caught in the mangle?

I'm beginning to wonder. For many years, I was told by one of my vast panoply of brothers that our grandmother got her (see title) caught in the mangle. They even showed me where it happened and described it in excruciating detail.

Then I met someone else who said the same thing happened to their grandmother.

Then another.

Then another.

Um. I was then beginning to wonder whether there was some catastrophic failure in the health and safety features of mangles. Then I googled the title phrase and found out that it is an expression.

I haven't laughed so much since grandma got her tits caught in the mangle.
