Does anyone know where I could find one or two (or more) examples of .net controllers that have too much going on in them?

I'm trying to create a demonstration for a talk that involves starting with an unruly mess of spaghetti code and works out how to get it into something more manageable.

I'd prefer not to have to fabricate the spaghetti if possible. It would be nice to start with at least something _mostly_ realistic. I've been searching github but haven't had much success.
