Do you know anyone who is a stupid, churlish dolt?

Not personally. I try to avoid people like that. I see them all the time on TV, usually because they get elected.

On our ABC (Australian Broadcasting Corporation - independent publicly funded TV & radio)
there's been a comedy show running for years - Grumpy Old Men. Journos interview famous elderly men about how they feel about the various aspects of their lives. Then edit and splice together the results. Hilarious.
