Snakes* on a Swamp Thing.
from the back cover of The Comic Reader #172 (September 1979) – art by Mitch O’Connell
*Yes, I know there’s only one snake in the picture. Don’t poop on my joke.**
**And by “joke,” I mean “cultural reference in place of an actual joke.” See also Family Guy.***
***”Oh, damn! Oh no you didn’t!”
