Oh, you were referring to the old Thor comics?
Ah, I remember them from when I were a lad "Mjolnir to thy master !"... but actually I think he's referring to the TV show Stargate SG-1. The asgard are an ancient race who have become asexual clones (or something like that
) - but who still find time to safeguard the Earth from being conquered/destroyed by the evil Gua'ld.
The Tigers roared in Dublin - and I was there.
