Ok... I'm suddenly thinking of the Outer Limits episode "To Serve Man".
Mmmm... Human flesh...
But... kids... young, succulent, full of hormones.
Mmmmmmm... kiddie flesh!
It's the only thing I can think of, since they live in an atmosphere that is basically poison to us.
Which makes me think that our air is poison to them... War of the Worlds anyone? Quick! Someone sneeze in their intake valve! :)
Oh, and what hold does the 456 have over the British? How did they get them to give up kids in 1965 in the first place?
We're the big bad aliens! Give us kiddie flesh!
Fine! [zap zap zap] Hah hah! Die ingorant middle men! Die a flamey death, with lungs filled with poison.
Stop! Stop! Here! Take them! Take them! Do you need a bib?
Only if it attracts the ladies. Does the lobster on this make me look fat?
I am a sick, sick woman...
You know, since I think they eat them, there's a good chance they don't.
I know, they put them on a planet full of wonder and fun and rainbows and unicorns.
Or is it kiddie-flesh eating unicorns?
