So it just happened, about 60 seconds ago. I am in the kitchen, and I hear a "tink, tink, PLOP!" from the bathroom. My brush, which I generally keep on a shelving unit above the toilet, fell from it's stand and directly into the liquid bacteria trap. I'm not sure what prompted its fall, but I think I may need a new brush... Luckily it was my $9 Omega, and not something more valuable.
