A duck's quack doesn't echo,
and no one knows why.

Dentists have recommended that a toothbrush
be kept at least six (6) feet away from
a toilet to avoid airborne particles
resulting from the flush.

(I keep my toothbrush in the living room now!)

These ones were both tested by the Mythbusters --

Does a Duck's Quack Echo?
This myth originated in lists of "Random Facts" distributed over the internet.
A duck's quack does not echo.
Busted
When examined by an audio-expert, it was found that the echo was "swallowed" by the original quack, due to the very similar acoustic structure between the quack and the echo. Because of this, it may be difficult to tell where the quack ends and the echo begins. (This was also tested in the British show: Brainiac: Science Abuse)

Toothbrush Surprise
Fecal coliforms bacteria can grow in toothbrush bristles.
Partly Confirmed
Fecal coliforms were indeed found on all the test brushes, including the control ones. However, none were of a level high enough to be dangerous, and experts confirm that such coliforms were impossible to completely avoid.

I remember watching this show, and they built a really complicated rack in the bathroom to hold a bunch of toothbrushes, and then used two of their own for a month to test. Also, they put 2 clean toothbrushes under glass in the kitchen far away from the bathroom as well. All brushes showed coliforms, even the ones in the kitchen that had no contact with the bathroom!
