A plunger is a tool for dislodging turds and detritus in a toilet

I've always found that weird, do people really use plungers for that?

The toilet brush is a much better tool for unclogging the average toilet.

The plunger is actually meant to unclog sinks as far as I can tell, since it can attach much better to the sink and through its action can create pressure to unclog the much smaller sink drain pipe.
