Weird Bathroom (or other) Graffiti!

In a porta potty at the hoover dam i saw

“this is a teepee to go peepee,
not a wigwan to neat your tom tom.”

And in a pizza place in new york

“Oedipus you mother fucker!”

Back in high school, a friend and I ventured into the boy’s bathroom on a dare, and didn’t stay long enough to read all the graffiti, but I do remember a line near the ceiling that said “If you can hit this line, the fire dept. needs you” I don’t know why I still remember that, cause most of my teenage years are a blur.
