It was Transformers in our house.  Their catch phrase was 'Transformers, more than meets the eye'.  It came out as 'morfen meefy I'  from our young lad.  Still gets shouted at the TV occasionally.  He's over 30 now and still watches Thundercats!

I think it was Transformers robots in disguise JJB.

You are quite  right Mikey, that was also one of their slogans,   but if you goggle 'Transformers, more than meets the eye' you'll find the cartoon series that the lad loved, which had the song at the start with 'morfen meefy i' .  I think it came out in 1984.
