Mork & Mindy (1978)

Yes Sir, That's My Baby - S1-E19

Continuity mistake: In the scene in bus station, when Mork is talking to the drunk sleeping person, he's holding a bag, there's a shot of the FBI man, and the next shot of Mork, he's not holding the bag anymore.

Mork's Mixed Emotions - S1-E20

Orson: You opened the door to your emotions, didn't you?
Mork: Yes, Sir.
Orson: You realise you've broken the highest Orkan law. It is my duty to report you to the Council.
Mork: I understand. But I don't regret what I've done, sir. You see, for the first time in my life, I feel really alive, I feel fantastic! Oh, I wish you could try it! I wish you could feel some of the things I've been feeling!
Orson: Impossible. I could never do that. They'd throw me in prison.
Mork: Oh, I don't mean to be disrespectful, your immenseness, but until you can marvel at a rainbow after a storm or rejoice at seeing a baby walk for the first time, or hold someone and have them feel the same warmth inside as you feel close to them outside - until you can do these things, aren't you already in prison?

Show generally

Question: I may have this scenario slightly wrong, since I haven't seen it since the show was brand-new, but is there a scene in one episode where Mork (just him-no egg) falls from the sky and into a lake or some kind of body of water? I slightly remember this as a kid but wanted to see if I was right. Anyone know what episode this was from?
