Bill, Mike, & Kevin should use their own theater seat sillouettes on screen

I just think that it was an integral part to a riffing experience as i watched it with my dad growing up. It would be nice to see it used again if possible

I always felt like the silhouettes were the best part of the original MST3K formula. It also makes the riffing more genuine; the voices of mike, bill, kevin, would give the impression that they're coming from a character on screen

The silhouettes are a copyright of Joel and MST3k. Rifftrax can't use them and even if they could the newer movies they riff, silhouettes would not be allowed again due to copyright infringement.
This has been discussed for years on this forum. There's a search you can pull up about this discussion under 'MST3k Silhouettes' and some even created their own silhouettes: http://forum.rifftrax.com/index.php?action=search2
