I'm not a regular reader of Doonesbury anymore, but I happened to see last Sunday's strip posted on a professor's door and Gary Trudeau is still brilliant.
It's similar to the argument I have used against Creationist hypocrisy, but in Trudeau's hands it's succinct, pointed, and laugh-out-loud funny. Just as there are supposedly no atheists in foxholes, there are few stick-to-their-principles Creationists in doctors' offices.
What really put it over the top for me is that I just took my pharmacology final last Friday and tuberculosis meds were on it. Streptomycin for TB, ludicrous!
