I think the coolest gift I can remember getting for Christmas was a TOBOR. Robot spelled backwards. It had a little clicker for a remote that would send it turning backwards in a circle until you clicked it again and then it would go forward. It had a top secret briefcase that you could try to pick up with Tobor's left hand.
Broke his antennae the first night I had it!!! Those were the days. Man I really loved playing with that thing.
