Frank Nelson on The Tamer:
"The Tamer is the best idea I have ever had - originally designed back in 1975 - two decorative figures interacting with each other. The Tamer cracks his whip twice and gets a refusal each time from the animal who shakes his head from side to side while his tail rotates. On the third crack of the whip however, the animal accepts the command and nods his head and does his trick - putting his head into the Tamer's mouth."
