A guy I work with (who shall remain nameless) was sitting on a toilet (going, uh, number two).  I was in the bathroom also, which seemed to be in a private residence.  He calmed watched and commented as I tried on different pairs of underwear, apparently preparing for some kind of outing.  I was even taking them off and putting on new ones right in front of him - something I would not be inclined to do during waking hours.
