Lessee, so an 18-year-old getting pregnant by her boyfriend means she's sleazy and wants to fuck baseball players or total strangers. Perhaps the New York Yankees could pull a train, ain't that a larf, har har har. Oh, and that "slutty stewardess" mother of hers, that's another pile of steaming humor. Because like those Dangerous Housewives, both Sarah and her daughter have vaginas, which must mean that they've left themselves open to talk about their sex lives.

Now, I wonder how Dave resolves this with being an unmarried father - does that mean his girlfriend also has a secret craving for the Yankees, or worse, the Mets?

It would be one thing if Letterman would know when to shut up, but his half-ass apology just burns it. Plenty of people ask for ridicule, but the younger Palin simply made an underage mistake with her boyfriend - why that gives Letterman the right to make tasteless sexist jokes is hard to figure. But when you bomb, don't double down.
