This is the sort of thing I would do if I wasn’t so busy…and so lazy: A guy named Andrew COUNTED EVERY RIFF IN EVERY EPISODE. He also timed every episode. The result: a boggling statistic: riffs per minute.
Oh, and here’s a ton of data.
This statistic is, admittedly, ultimately meaningless: more riffs doesn’t necessarily mean better. But still, I love the fact that somebody spent time dissecting the episodes like this. It’s definitely heading for Ward E.

Andrew, we salute you! Excelsior!
