Do you know any good limericks?

We all know the one about the man from Nantucket. I have no desire to meet him, by the way. I used to have a book with a really funny collection. There were hundreds and hundreds. Sadly, it’s gone and my memory, while great, is kinda short. I can remember one that I read in the Foundation series by Isaac Asimov, as told by a cyborg;
There once was a cyborg named Sue.
Who wound up on a scrap heap, it’s true.
What a vicious caprice, she was missing a piece.
And perished for want of a screw.
I’d love to rebuild my collection again, so any contributions would be most welcome.
