I know I've been blogging a lot of signs recently, but too bad. When you figure out a way to beam all of quantum mechanics into my head at once I'll have more interesting posts.
In any case, here's another sign I found while wandering around the bowels of a City College building:What in the world are they storing in there? Everything? Are they missing anything dangerous? I mean, they even scrawled on a "Please do not block door." Maybe I'll buy a "Beware of Dog" or a "No Lifeguard on Duty" sign and stick it there, just to cover all bases.
