Other people will judge you by those you associate with.

Karma is a whore who requires payment up front (many thanks to LW for her eloquence ).

Plaid pants and safety pins do not a punk make.

Communism is a good idea in theory, but it doesn’t work so well in practice.  People think that they’re all going to be equally rich when in fact they’re all made equally poor.

Laughter really is the best medicine.

Always treat things that you borrow better than you’d treat your own possessions.

There’s no shame in crying; tears can be very therapeutic.

You can lead a horse to water but a pencil must be lead (that's a Dave-ism)
