Coming down the world turned over

My brother made me recall the title of a movie with the following description:

2 brothers living with a nerd uncle who sells Tupperware.

Me (in less than a second): Napolean Dynamite?
Him: YEAH! But i can't believe you managed with a description like that!

Disclaimer: The uncle was not selling Tupperware, if i remember correctly, but some wok and pan stuff.
