It's not often I tell you about a spring finale this early, but what Fox's The Simpsons has lined up to cap its 24th season sounds out-of-this-world fun.

"We're going to be visiting Kang and Kodos' home planet," teases executive producer Al Jean, who cowrote the episode. "This is the first time we've used the aliens not for a Halloween episode. It will be really funny to see where they live and what they do."
