AutoZone should have bought out RadioShack so they can legally change their name back to AutoShack. I still remember the spat that Tandy Corporporation ("Goliath") had with AutoShack ("David") back in the 1980s which forced them to change their name to AutoZone. It would have been sweet revenge had AutoZone thought about buying up RadioShack that the "David" and "Goliath" roles are now reversed.
When I would hear the slogan in the AutoZone commercials, I would say "Get in the Shack, AutoShack!" as if I was living in an alternate reality where AutoZone kept their original name.
