Tombstone Tuesday - A Cowboy's Gravestone?

It's Tombstone Tuesday, time to post one of the pictures of gravestones in my collection. Unfortunately, I ran out of pictures of my own ancestral families months ago, so I'm posting pictures of "interesting" gravestones that I've collected over the years.

Some people think that this is the coolest gravestone saying ever:

I've seen this before, and wondered if it was real, or if it was a faux gravestone created by a clever photo artist. It is real, and I recently found out whose gravestone it is. It was erected to commemorate a World War II Navy sailor, Russell J. Larsen (1921-1983) and is standing in the Logan City Cemetery in Logan, Cache County, Utah. The entry on Find-A-Grave has photographs of both sides of the stone.

I wonder if he wrote this epitaph himself, or if his good buddies heard him say it and put it on his gravestone?
