This topic is about a rather unusual and humorous story involving a colostomy bag during a trucking trip in South Australia. The storyteller shares an experience with his friend, "Big Mal," who has a colostomy. Here's what happened:

1. While driving, Mal threw a full colostomy pouch out of the truck window, and it accidentally hit a caravan's windscreen, creating quite a mess.
2. Mal stopped the truck and approached the elderly driver of the caravan, pretending not to know what happened. He jokingly suggested that a "big bird" might have caused the mess.
3. The elderly driver, surprised and overwhelmed by the smell, agreed with Mal's explanation, while Mal tried hard not to laugh.

In addition to this incident, the storyteller mentions another prank by Mal:

- Mal once hid a full ostomy bag under the mattress in a sleeper cab of a driver he didn't like. The smell lingered for weeks until it was discovered, and Mal faced consequences when he was identified as the prankster.
