I hit upon the idea of eating on the floor of the bathroom at least five years ago. While sitting cross-legged on the floor mat next to the sink, I peruse EntertainMeWeakly
(check it: the cast of Seinfeld is reuniting this fall on HBO's "Curb Your Enthusiasm")
or Snoozeweek as I eat a NutriGrain bar (or an Oreo Cakester if I'm jonesing for some chocolate). On other evenings, I'll microwave some Pillsbury homestyle pancakes and make sure to put plenty of syrup on them.
I sometimes even eat my dinner in there; the white noise offered by the bathroom fan is a nice reprieve from the TV blaring as my wife watches stuff like Nancy Grace and "Fried Green Tomatoes". The bright lights given off by the vanity also make it much easier for me to read.
