I realized halfway through the task of draining the toilet that I didn't know how. I'd never done it before. I've drained the tank plenty of times, but not the toilet bowl itself.
It all started after I had to use a "snake" to unclog it. The snake left marks. My wife bought some "Bartenders Friend" or whatever type of cleaner. But first, the bowl needs to be drained. Anyway, here's the solution.
Although this seems to be a simple question the answer is actually somewhat tricky.
