Pooping at work is a good thing:
1) It's against the company's water bill, not yours
2) Less toilet paper usage (can be negative since corporate toilet paper is usually recycled 60 grit sand paper)
3) The power of an industrial toilet can suck a small child. Who cares if you have 3 pounds of cheese the night before.
4) If you blow ass all over the place, who cares... janitor has to clean up the poo spew
5) Stink factor is not a good thing when company is over so get rid of the power bomb at work.
Course I consider Tim's toilet fair game for all above activities.
