Ok, for this you are going to need a can of baked beans and a beer.
Preferable a big one.
Open up the can, pour the baker beans into a container for cooking, but DON'T throw out the can, was it... you will need it later.
Pop the baked beans on the stove and stir them regularly to keep then from sticking and burning.
Once they are cooked, serve them up with a beer.
EAT UP!
Once your done, grab that tin can from before and punch a hole in the bottom of it. You will have about 10min for this part of the excersie from the time you finish eating the baked beans.
Make sure that if you feel flatulance pressure you chench and keep it in.
Once you have a decent hole in the bottom of your tin can, about an inch in diameter put the can to your bung hole and release...
