I bought a snake, removed the toilet, snaked the drain, and my old toilet
works fine now. Cost? Less than $30 for one wax rim and a Wal-Mart toilet
snake...

See there? All that expensive dental school paid off. You gained access to the
cavity, cleaned out the rotten debris, and sealed it all back up nice and
proper. :-)

You could have learned all that as an apprentice plumber, billed more for the
first half hour, and had lower overhead to boot.
