What's brown and sounds like a bell? <br />
"you ring my bellllllllllll......you ring my bell." <br />
A long time ago, it wasn't unheard of to bury people alive. Headstones had a bell attached to a piece of string that was attached to the "deceased" finger. If they were actually alive they could ring the bell and the person on "Graveyard shift" could dig them out. <br />
So I've read anyhow.
It depends, every bell is different. ;)

Oddly enough the thing on a sailboat that is actually called a rope it the one that rings the bell.
