I was making scouse (stew) years ago in the pressure cooker, everything was going so well until i heard this strange noise coming from the kitchen i ran out (which was a feat in itself as i had gone 2 days over my due date for my sons birth and was huge) only to see the full contents of the pan spurting up through the tiny presssure hole in the lid, it covered my ceiling and stuck fast. Still don't know what happened, scared the life out of me though and still went 2 more days over, think he was scared to come out after that. Lol. xxx
