This item in Deadspin caught our eye: The NBA is said to be handing out warning cards to unruly fans telling them to clean up their behavior. They look like this:

As a practical matter, we have to imagine it would be hard to find the same fan behaving poorly at a different game, but within the same game? It seems to be a fairly effective way to keep the cheap shot artists and real loudmouths at bay.

It also makes us wonder how many such cards we might have received in our younger, more heckling-friendly years as a fan of many sports. We're pretty sure Malik Rose wishes we had had been given one during the 1999 playoffs against the Wolves.

Your thoughts, please, in the comments.
