Irony

Having been to my requisite share of men's rooms I've seen my share of cartoon anatomy and pithy sayings like "If you can pee above this line the fire department is looking for you". What I haven't seen however is a water cup sitting next to a half used roll of toilet paper above the commode...

So, I'm confused. I snapped this photo near downtown Seattle over the weekend.

On my way this weekend from Bale Breakers (Is Field 41 the best beer in the world or what?) to the Fresh Hops Ale Festival I snapped this pic at a stop sign. Can someone explain to me why a muffler center has a gun for a sign? Yeah I get it's called Bonnie & Clyde but the only thing I can think of is I don't want my muffler to sound like gun shots going off...
