Forum:Help! What episode is this?

Can anyone remember the episode of The Simpsons where there is a meltdown or power outage or something and Mr Burns goes out to this shack in the desert somewhere to turn something on or off and as he enters the shack a dog comes in to greet him and he kicks it and yells at it? I need to reference this for a paper i'm writing and I can't remember which episode it happens in.
