Best Buy threatens blogger over someone else’s parody

Best Buy threatens blogger over someone else’s parody:

Best Buy sent a cease and desist letter to blogger Scott Beale (Laughing Squid) for having had the audacity to blog news that prankster/comedy troupe Improv Everywhere selling t-shirts that were a parody of the Best Buy brand. Whether or not the parody is legally in the clear is one matter, but Best Buy nastygramming Beale for simply blogging about it — not selling the shirts or participating directly? IANAL, but seems *way* out of line. Above, the parody logo that appeared on the t-shirts in question.
