This is a 4 Power Bar Law and Order

I freely admit to being a huge Law & Order fan. Before those bigwig executives got wise, there was a time when you could watch L&O (that's what we diehards call it) on something like ten different stations at all hours of the day. Now it's pretty much down to NBC and TNT, which is actually fine with me because TNT airs L&O right when I need it on the treadmill.

But they often advertise that they're running a "mini-marathon," which begs the question: what's the least number of consecutive episodes required in order for something to be a TV mini-marathon? And what's the dividing line between a mini-marathon and a full-fledged, staple-yourself-to-the-couch-and-insert-a-catheter-because-you're-not-going-anywhere marathon?

Also, who begs for questions?
