Emergency Pooh

You know when you go to a restaurant and you eat a shed load of food, and you feel like you've eaten too much. You sit there with a bloated stomach and feel really uncomfortable.

There is a hidden body function that few people know about which is ideal for dealing with this; called the "Emergency Pooh".

This is a switch in the body which is triggered once too much food has been consumed, which basically actions an emergency pooh (a quickfire pooh to get rid of the waste which has been taken on board).

Mark: Oh man I've eaten way too much, my gut is going to explode
Mike: Don't worry mate, just action an Emergency Pooh!
