Fame

I had dinner this evening in a Boston's Restaurant in Coralville, Iowa. While I was in the restroom (a nice remodeled restroom) I noticed that someone had scrated their initials into the top if the urinal. I guess I have a couple of questions: (1) Why? and, (2) What were they thinking - that they'd gain some sort of urinal fame? Well, Mr. SU and Mr. MR you have found fame on the internet...
