Its
your monument. Have anything you please. I'd go with something that makes a real fashion statement, personally. Tell your kids that you want a pyramid or the Sphinx constructed in your honor. What the hell. You'll be dead and it will be their problem honoring your final wishes. You can depart this world chuckling over their chagrin. It will be your payback to them for their teenaged years.
Hope you feel better soon, by the way.
