There are also some nasty casteist ones. I remember hearing one a long time
ago from a relative, intending to mean you can't expect perfection; there
will always be something bad around. But it likened the bad with
'Maharvaddo' i.e.the settlement of the Mahars!
Gaanv thayn maharvaddo or some such -- where there is a village, there will
be a maharvaddo...
Had heard something similar in Marathi too.
