One thing I neglected to mention during my review of Rifftrax Live: Sharknado is that the guys started the show, as they often do, by riffing an old short. This one was an “educational” film called A Case of Spring Fever. As it turns out, this one had been riffed back in the MST3K days. I found it on Youtube the other day. The riffs they did last week were completely different than the MST3K treatment. Here’s the original.
