I don't think you're being sensitive. Like some of Jon's other questions (the one about most frequently buzzed Super Password letters comes to mind), I just don't know whether the answer is as easily accessible or cut and dry as he thinks it is. I mean, in the States, TPiR has been interrupted several times for a presidential speech, not just Obama.
Yeah, we pull some obscure trivia out of whatever orifice, but sometimes there's just some stuff nobody is going to know.
