It is so sad when the stuck valve handle finally breaks off in one's hands...

No one has posted this old plumbing limerick, possibly because it has no relevance to the problem at hand:

There was a young plumber from Paris,
Who was plumbing his girl by the sea;
Said she, "Stop plumbing!
I hear someone coming,"
"That's not someone," he said,
"That's me!"

Cheerily,
Charley Noble
