You want to be buried at Sea?

This retired Navy guy has three of his friends over to play cards on night.

Retired Sailor: Hey woman, get me and each of my buddies a beer.
Woman: You are always ordering me around like I am your servant. I liked it better when you were out on deployment on the high seas. I can't wait until you die. I am going to stomp all over your grade you grouchy old man.
Retired Sailor: Just get the beers and shut up old bitty.
Woman: I'll get your beer alright just hold you damn horses.
Another guy at the card table: Doesn't that bother you that she talks about stomping on your grave after you die. That would freak me out.
Retired Sailor: Not really, I could care less
Another guy at the card table: Why doesn't it bother you?
Retire Sailor: I plan to be buried at sea at least a couple hundred miles out. Let her stomp on my grave all she wants!
