I have so many. let's begin
Guy at work was about 300 lbs and worked in support. Every day around noon (I'm told) he would go to the bathroom to do a little numero dos. He always grunted and yelled throughout the process. His nickname with all the guys was "the screamer" (he also jerked off in the bathroom from time to time I'm told)
Second Story. A manager from another team apparently started doing testosterone shots himself. He also asked one of his reps to help him with it, downstairs, in the bathroom. One of the guys on my team was in the stall next to them one day and overheard it all. Thats how we know. Great manager besides that.
what's your story you prob wouldn't mind forgetting?
