Three flies in a trashcan get trapped overnight in a bathroom. The first fly goes to the sink, the second fly stays in the tub, and the third fly chooses the toilet.
The next morning, all the exhausted flies gather back in the garbage can.
The first fly says, "I'm exhausted! I almost got washed down the drain."
The second fly says, "I almost got squashed by feet in the shower!"
The third fly says, "The toilet was fine until it suddenly got dark. First, I heard thunder, then it started to rain, and if it weren't for that big brown log, I surely would have drowned."
