Pondering Beetle Bailey

Beetle Bailey, 2013-06-17.

Sarge doesn't know what zombies are. In the real world, everyone knows what zombies are. The only places where people have never heard of zombies are zombie stories. Look at The Walking Dead. They call them "walkers" because they've never heard of zombies. If Sarge doesn't know what zombies are, that probably means Beetle Bailey is the setting for a zombie story, but pre-zombie-outbreak. The fact that Beetle is now watching a show about zombies means that the outbreak is probably imminent and he'll be the first to realise what's going on because he saw that show. It's the only possible explanation.
