When you hold your poop in so long that you die, upon death your colon explodes much like an explosion of watermelon with a quarter stick of dynamite.
I would ask how she died inspector, but I can see by the color of the walls that it was Constipanious Combustion again. That's the third one this week.

Financial Combustion is a phenomenon that is best described and often related to large companies, like Wal-Mart, that move in and invade your business territory.
First sparks are seen coming from your battered store as your skinny wife and hungry children watch in horror as flames engulf your business premise completely until only fireman and ashes are visible.
This occurs when your businesses are unfortunately in the same neigborhood.
Followed by a desperate call to your insurance company.
This also applies to neigborhoods were Homo-Depot, Cocksco, resturants like Mc Pukes, and Grim Hortons make the move on ya!
