I can't remember the last time I saw one and I have Prime an' 'ting too.
Perhaps I accidentally have the right options set without realising or something.
On a GT related note, I did read a BBC news 'article' about the launch of GT and it seemed noticeably butthurt and pitifully childish, decrying the big budget 'cinematic' opening to the show - like you're going to launch a new flagship show with a pitiful, weaselly cheapass intro; ah yes, BBC.
If you've not watched GT yet, it's pretty much Top Gear. With a nice budget. As you'd expect really.
