Question for Dr Barnett (The Flu)

Dear Dr B

There is a medical issue that has had me thinking for a long time. If
I am busting to do a bowel motion and hold it for a while  when I
finally get to a toilet as I lower my bottom onto the seat I let out a
loud fart followed by the product.

I always thought the product would be blocking the anal hole which
would mean the product would come before the fart. Does this happen to
anyone else or just me?

Regards
Gordon Lightfoot III

Recently I was on the train listening to my walkman and farted. The
gentleman in the front of me turned and said something, I could see
everyone laughing. I removed my headphones and asked him to repeat. He
said the next train down that line will be carrying the goods.
What a funny saying.
