Yeah, that was already a scheduled break. They might've killed 20 seconds or so with the outro and intro, but that's about it.
For all its flaws, I thing Bill Engvall's Lingo shows that a sufficiently talented host can give you a good bit of editing room on a self-contained show. From appearances, I'm guessing that Bill did a fair amount of chatting with the contestants in every episode, which could all be left in if the contestants were guessing words quickly, and edited out when there was more struggling.
