Don't Think We're in Kansas - phantisma
An interesting crossover fic with Sam and Dean being rescued from an alien planet by Colonel John Sheppard and crew. Unfortunately the 'Sagare' have committed the Winchesters to slavery as a result of their trespassing and John has to buy the guys in order to release them. There follows a bonding ceremony that ties the trio together using alien technology.
