Tonight I think I might of topped off another cringe moment.
SWMBO is in work and I am home alone (well the little one is in bed) anyway, she has forgotten her keys so she sent me a text so that I have to wait up until she gets home, She is a alcohol beverage logistics technician*, So as it got to about closing time and sometimes she finishes early depending on how busy she is, she should be home at any time.
So my body decides that it needs a bowel movement, so I sit upon my throne and give birth to a rather splendid brown trout (can provide a pic if needed) and as I can feel another one in the birthing canal I set to work. At this point there is a soft knocking on the door. decision moment, do I wipe sort myself out before going to the door or do I cover up and scamper to the door let her in and then return to the job at hand. So I decided to go for the latter option (as we live in a flat it is only about 6 meters to the front door from the toilet.) So I stand up, pull my undergarments up, and waddle to the door like a penguin with my trousers around my ankles. Throws the door open to find nexts doors girlfriend at the door 
oh the shame.

I had to build the story up.
what happened next is that she kept looking me up and down while I was trying to unobtrusively pull my trousers up. However she did politely keep talking.
