Grave & Deathly Humour
People who can laugh at life and at themselves are fun people. Death is a serious thing, but you can pass on with character and wit, or any way you want as long as you have sorted out your afterlife during your lifetime. Some might say grave humour is in bad taste, ah, shaddup already, go dig a hole and plant yourself. My favourite is the last one... I told you so... so many times!!!
At least when your family and friends visit your grave, they smile and remember what a character you were.
