Little Billy walks in on his parents as they're having sex in the missionary position. Mum is really embarrassed and says:

"It's OK Billy, Daddy's just pumping me back up a bit, I'm a little bit deflated this morning".

Billy replies:

"Woah, you must have a serious puncture Mam, I heard Mr Collins from next door pumping you up for most of the night while Dad was at work."
