"Robert Downey Jr (who was looking super dapper) was on the [David Letterman] show promoting Sherlock Holmes" reports Will Clark World. "... Letterman asked him if they were playing up the gay content (in Sherlock) as much as had been suggested in the press. Naturally, David couldn't quite find the right word/phrase how to ask this and so Robert just said 'you mean, are they homos?'... Letterman feebly added some comment about Watson having a fiancee... Robert did chime in 'maybe she's just his beard.'"
