In the first season of Rick and Morty, Season 1 Episode 06: Rick potion#9, when everyone except the Smiths are cronenberged, Beth and Jerry stop on their way home to kill some monsters. Here's the clip:
Beth: [loads her shotgun after killing the last of the cronenbergs]
Jerry: I wish that shotgun was my penis.
Beth: If it were, you could call me Ernest Hemingway.
Jerry: I don't get it, and I don't need to.
Just like Jerry, I didn't get that reference to Hemingway either. What was that reference about?
