I like this one:
Here lies the body of Martha Dias,
Who was always uneasy, but not over pious;
She lived to the age of three score and ten,
And gave that to the worms she refused to the men.
However, I don't know how much I like this one:
Every once in a while I forget.
I think it's because I'm on another message board also with v-bulletin and siggys are automatic unless you manually turn them off.
