First off, thanks to Marlena for returning to blog to a territory so close to every Mastandrea's heart....and colon. So lets get right down to business.
Was the toilet clogged by the paper or by the log?
This is a very important question and the guilty party is being very sketchy on details. Three inches may not be an enormous length for a log, but it would be a spectacular diameter. A turd of such impressive girth would certainly clog the pipe and cause a backflow. If this is actually the case, be not embarassed, BE PROUD. Be thankful there was a house of witnesses to such a historic event!
Oh, how I love discussing crap.
