Well, that's what you like to call him, in your head. But you're pretty sure that's not his real name.
Oh, yes, of course! You should have remembered that, because he likes to call himself "The Prez" because he has the same name as nineteenth president of the United States Rutherford B. Hayes. (Well, the same first and last names, anyway... you're not sure whether his middle initial is B.) This is just one of many annoying things he does. I mean, seriously, it's not like he has the same name as one of the important presidents. Nobody cares about Rutherford B. Hayes!
Well, yeah, obviously you're not going to talk to him while you're standing here at the urinals. But you won't be standing here forever. Far too soon, you'll be finished here, and then you'll both go to wash your hands, and conversation will be inevitable.
Unless... unless maybe you can think of some sort of CLEVER RUSE to avoid talking to this jerk?
