In case you missed it, here are the highlights from John McCain's appearance on David Letterman last night. Warning: It is wildly less funny than McCain's legitimately hilarious performance at the Alfred E. Smith dinner -- but still entertaining for all fans of "uncomfortable" and "awkward." (Sorry about the stupid ad at the top of this clip. Take that 30 seconds to reflect on how McCain was at one time a funny, and fairly decent politician before he was put under the spell of Karl Rove.)
