Take a familiar Stargate concept [character, ship, race, etc.] and change the name, background, etc. slightly and in a funny way.
Another mistake of the Ancients. While attempting to create humanity in the Milky Way, the Ancients accidentally created humans with blue skin. The Azurans survived the Ancients' attempt to destroy them and now, armed with Ancient technology that actually works as well as tactical smarts, plan to destroy humanity for being the Ancients' favourites. They also want to destroy us for constantly calling them Smurfs and wanting our children to watch them.
