I’ve been searching and watching a few Batman animated series episodes at a friend’s place since I barely have power or wi-fi and so far, I haven’t found yet the scene I’m looking for. Not even Google or wikis can help.

Scene:
Batman using his rope thing to catch someone by the legs and make them trip over a building.

Please, this time, I need help. What is the name of the first episode to feature such a scene?

If anyone is truly a Batman fan and into such things, please give me a sure answer. No guesses. It’s crucial. I don’t want to be left hanging on a thread.
