Have Rocket, Will Travel

The Stooges are janitors working at a space center who accidentally blast off to Venus. They encounter a talking unicorn, a giant fire-breathing tarantula, and an alien computer which has destroyed all life on the planet and creates three evil robot duplicates of the Stooges. When the boys return home triumphant, they are given a hero's welcome; a party in their honor becomes a free for all pie fight complicated by the arrival of the evil robots; our heroes and their unicorn friend managed to escape. The epilogue shows the Three Stooges riding on a rocket singing a monologue and ends with Moe getting plastered with cream pies by Larry and Joe!
