Unmarried guys, amiright? They wear gold chains and just don’t get anything about… never mind. It’s not much of a joke, which is par for the course when it comes to Marvin strips. More interesting is the depiction of hanging out at bars, which is standard for daily comics. The characters are clearly depressed to the point of despair, staring off into the middle distance and awaiting the inevitable embrace of death. There no wall decoration except for a tiny “exit” sign. Interesting artistic choice.
Jeff has a beer, obviously, but what’s his swinger friend drinking? Orange juice? A beaker of urine? No wonder he’s single.
