I've just fended one off.
Awake at silly O'clock, rumbling guts. Rolled over and went to release a fart under the duvet, it was quickly apparent that it wasn't going to be a fart.
Jumped out of bed and made it too the bog just in time. Swmbo would have gone ******* Banzai mental if I had shat the bed.
I'm sat downstairs with the dog just in case another offensive is launched my arse.
I'm staying awake.
Watch, and shoot.
