this was one of the better ones. plus it was a three parter a rarity among series even today. we see the joker and penguin combine forces. the second episode penguin is not there but he does come back for the third. it has to do with the zodiac
watched this one when i was growing up and still love this episode. classic batman with the original joker and penguin. nobody does three parters anymore. even did cliff hangers on the two episodes. this one was a little better than the clam but in the 60's props were cheap
