In 2009, the European version of Cartoon Network's sister TV channel Boomerang used the scene from the beginning of this episode (the one showing Huck dressed as a doctor walking alongside the wall) in their promo for the Huckleberry Hound show.
This is the fourth time Huck goes up against a lion. It has also happened in episodes 3, "Lion-Hearted Huck", 19, "Lion Tamer Huck", and 27, "Somebody's Lion".
Huck: (after the lion ties him up) First lion I ever did see that can tie a decent knot.
Huck: Now mister Lion, I'm here to help. (lion attacks) Help!
