Marshall and his family are new to Eerie Indiana, one of their neighbours comes around to say hello and to introduce them to the Foreverware Tupperware. It turns out it can keep more than just food fresh forever.
As an Introduction it's nice to have something that just jumps right in there with a surreal version of The Burbs almost. Where as keeping young by coffin or hyperbolic chambers isn't new, the idea and imagery of a giant Tupperware container is just bizarre. That is what is great about this show, it isn't afraid to be surreal, in fact it relishes in it. The Tupperware party is also very freaky as all of them seem to be from the 60s or 70s. Marshall's Mum is obviously signing up for more than Tupperware.
So not the strongest episode but introduces many elements that run through the series and the twins are just great. I need to watch the boxset in full again though cos I'm sure they pop up now and again.
