The Different Types of Water Buffalo

There are four different kinds of water buffalo:

There's the kind that you find beneath rocks at the bottom of the dollar bin of your friendly neighborhood static dealer.

The second kind of water buffalo is the kind that clogs the filters of your pipes and produce such awful messes in airplane lavatories (these are not to be confused with bed buffalo, that make the mattresses lumpy).

The third kind of water buffalo pop up when you sneeze in an elevator, but only when the elevator is descending over the site where a unicorn barfed during a day of the week that has the letter 'r' in it.

The fourth kind of water buffalo is top-secret. I'm taking that knowledge with me to grave, buster. You can't be too careful about what you say.
