I guess I'm twisted but I think I've seen worse.

I have nothing against gay people but you have to admire how clever this back glass is:

Okay, we have the guy on the right in a LAVENDER jacket, hanging out in a lavender bar to boot. (The girls are all there to listen to the 80s and disco music) He's got this buxom hot blond across the table but does he care? Nope. He's got another hot lady six inches to his right and she might as well be made out of jell-o for all the attention he's paying to her.
Meanwhile, oops, Prospector Bob "accidentally" dropped his cards under the table. "Oopsie. I'll just crawl under this here table and mmmmpppppghghghghghmmmm." And now Lavender jacket is so distracted by whatever Bob was doing under there, he doesn't even notice the other two girls are plotting to cheat him.

Look closely at the girl and horse in the upper-right. She really likes that horse. I mean, wow, she REALLY likes that horse! It's just not natural, woman!

1 girl and 7 clowns. That's pretty messed up on its own, but they took it to a whole other level. Notice how the clown in the middle is crying? It's because he's having performance anxiety, so she's encouraging all the other clowns to laugh at him. All he can do is try to "cover up" by placing the accordion in his lap. What a sick dominatrix! Looking around the rest of the backglass we've got drugs, a guy in the lower left with what looks like a large branding iron, and a poor little dog who will suffer unimaginable indignities.
