I too prefer to be cremated, but, I do love me a fun rhyming epitaph, so here's some that I found amusing.
From a Scottish Graveyard:
The children of Israel wanted bread
And the Lord sent them manna.
Old clerk Wallace wanted a wife,
And the Devil sent him Anna.
On the Tombstone of an Accident Victim in the Uniontown, Pennsylvania Cemetary:
Here lies the body
of Jonathan Blake
Stepped on the gas
Instead of the brake.
On the Tombstone of Anna Hopewell in Enosburg Falls, Vermont:
Here lies the body of our Anna
Done to death by a banana.
It wasn't the fruit that laid her low,
But the skin of the thing that made her go.
On Fred's Tombstone, Don't Know Where:
Here lies good ol' Fred.
A great big rock fell on his head.
Unknown Tombstone:
Caught for a robbery that I blundered
And thrown in jail for my failed plunder
For breaking the locks
They put me in a box
And now I lie buried six feet under.
