Free idea for your War of the Worlds... The aliens look just like really nice washing machines, invading laundromats all over the world. At first it was just a stray sock, some underwear... Then dogs and cats, then people... Problem is, they do such a nice job getting stains out, you just hate to tell them they can't stay here on Earth... "But Garth, that thing ate my grandmother!" "I know Lydia, but have you seen my bluejeans? It actually got the grass stains out. They haven't looked this good in years!"
