do you ever get that feeling, when you are lying in bed?
no, not that one.
the feeling that you are about to let one fly.
but you can't really because it might spoil the mood.
or even wake your sleeping partner up, depending on the severity of the internal pressure.

so the question is, would you ...

a) let it rip and cheerfully accept responsibility?
b) clench your buttocks and implode?
c) run into another room and muffle it with a cushion?
d) let it happen and blame your partner?
