My chronology of restroom-based cellphone use continues:

Today at work at the urinal I hear, coming from the stall to my left, a man talking to no one in a loud voice, clearly on a cell phone. Then, in the middle of a sentence, the man stops and says:

"Can you hang on? I have to... um, hang on."

And then a pause, and the rustling, paper sound that can pretty much be only one thing. So I guess even though you think it's okay to use the phone on the can, you're not quite ready to just say,

"Hang on, I have to wipe."
