Stuffing packets from my humour buffer into my mouth driver...
Sometimes you really need to watch what you say -- a while back I had successfully dieted to the point that people meeting up with me afterwards would comment on my slim(mer) appearance.
"Hey Bob, you lost some weight?"
My immediate, untruthful and instantly-regretted answer was one word.
"Chemotherapy."
The really really bad thing was I did it more than once.
