Sure, the WWE is notoriously unscrupulous when it comes to who it will cross-market with, but I would think that the sanctity of the Muppets would keep them from getting roped into a dog-and-pony show such as this. Well, they weren’t.

TV boasts a long history of ill-advised guests appearances and promotional stunts. This Muppet one is just the latest, so take a look at the Muppet appearance and eight more. Then go take a shower.

Muppets on Monday Night Raw

As we’ll see, what seems like an inconsequential decision at the time to include an up-and-coming band in a TV show can often prove profoundly bizarre further down the line. The Flaming Lips have established themselves as a pillar of millennial alternative culture and 90210…not so much.

Before they had hacked out an identity, they were pimping their hit “She Don’t Use Jelly” everywhere they could. And this video proves that point beyond a shadow of a doubt.

Harlem Globetrotters on Scooby Doo

In the 1970’s, the Harlem Globetrotters got their own cartoon with Hanna-Barbera. Fair enough. I guess they were popular enough to carry their own show. However, in an attempt to cross-promote, Hanna-Barbera shoehorned the Globetrotters into a Scooby-Doo crossover, i understand the need to market your show, but this happened on no less than three separate occasions.

Individually, I guess the moves make sense in context. Sort of. But even as an eight year-old in the 80’s, I was caught off guard watching these reruns, wondering why the hell the Harlem Globetrotters were being called in to investigate haunted amusement parks.

Here a seven rock stars who won’t win any acting prizes and will have to find comfort in their Grammy Awards and throngs of screaming fans.

Gwar, Empire Records

If you give it a good listen, this one doesn’t fall on Gwar’s shoulders. They actually redubbed the voice of Oderus Urungus because, “I refused to do the stupid lines they had so they just took out my voice and put in what they needed. I had no idea until I saw it!”

It’s too bad the other rock and roll stars on this list can’t say the same.

The Ramones, Rock N’ Roll High School

As awesome as The Ramones are, they should stick to drunkenly stumbling about the stage and recording studio, not a film set.

Tom Petty, The Postman

Of course, Tom Petty survives the apocalypse and goes on to manage a settlement. And I’m not talking about Tom Petty playing a guy who manages a settlement. I’m talking about Tom Petty playing Tom Petty managing a settlement.  I guess it’s not that far fetched when you consider how he kept the Heartbreakers in line all those years.
