> Hook-up Truck™ is a registered trademark, in case you hadn't figured that out yet.

I'm having my doubts about this statement purely because they're not using the ® symbol that actually means registered trademark. However, searching the trademark database actually does reveal that it is registered[0].

I suppose Shaggin' Wagon was already registered.
