Late last night, after listening to the second episode (for a second time - it holds up very well!), I made a list of possible ideas for future episodes of the show. I accidentally deleted the document (argh!) but I still remember several things I wrote. My favorite was one that Luke suggested, which was a Muppet impressions contest! That idea stemmed from reading the summary of MuppetFest by Tom Holste here on Muppet Central. It was supposedly going to happen at MuppetFest, but did not. This would be a great way to revive Tom's great idea.
I really think it could work. People who wanted to participate could send in their impressions through the MuppetCast voicemail, and you could run them all in an episode (although you'd probably have to find a way to narrow down the number of impressions in that episode), and then we, the people, could vote on our favorites through the voicemail service. It's genius, I tell ya! Also, the winners could receive something special. Like candies.
