David Letterman's War Against John McCain Day 4: "Good Thing John McCain Blew Me Off To Go Save The Economy"

Tuesday night, David Letterman kept his war with John McCain raging strong, weaving another McCain joke into his monologue (that's 4 shows in a row, not counting the Friday show which was seemingly pre-taped earlier in the week).

"Yesterday the stock market...suffered its biggest one-day drop in history....And I'm telling you, boy, it's a good thing John McCain blew me off to go save the economy. Thank god is all I can say!"
