If your in Spain and playing some of Naughty Dog's Uncharted: Drake's Fortune, then maybe you've come across this tomb. It reads "Si usted está leyendo esta piedra sepulcral usted es un nerd enorme. Consiga por favor una vida y consiga una novia." That translates to the below.
"If you are reading this grave, you're a huge nerd. Please get a life and a girlfriend."
It's not that nice, but a good find to whoever found it.
