What are the greatest episodes in TV history?

One would be the house of cards show from The Brady Bunch.

I mean, building that house was hard for the Brady kids, but watching them do it was just as nerve-racking.

Final episode of M*A*S*H comes to mind. Goodbye, Farewell and Amen.

I would say the episode of the V miniseries when the aliens are revealed to NOT be human-like. Also, the episode of Ed when he and Julie Bowen's character finally marry.

The episode of Home Improvement where Tim drops the huge beam on Jill's car.

Hey Arnold: Parents Day

As soon as I saw this thread this episode jumped right into my mind. 

A classic episode for me would be Full House when they are doing the telethon.  I love how Mike Love pops in at the end and performs "Be True to Your School."

The Masters of the Universe episode, "The Problem With Power". He-Man faces the idea that his actions killed somebody, and he gives up the power of He-Man (but it was all a ruse by Skeletor). Just an example of how deep the writers would go, even though it was really just a 30 minute commercial for toys to some.

The chocolate factory episode from I Love Lucy.



Speeeeedddddd it up a littllllllllllllleeeeee!!!!!!!!

The Little House on the Prairie episode where Mary goes blind.

 

No matter how many times I'm asked this question, I always revert back to my 8 year old self and go bonkers over the Premiere Episode of "Lost in Space", from 1965. Creator Irwin Allen had a knack for making shows that absolutely rocked with 60's kids - even in glorious black & white!

That scene with the Robot trying to destroy the Jupiter 2 was beyond awesome in 1965. The Robot's goal was to knock out the cabin pressure control module and create a breach in the ship's hull. The fun part was watching Guy Williams, as "John Robinson", fall down repeatedly in a most embarrassing, and funny, way!

Remember, Guy Williams had just signed with 20th Century-Fox after his work for Walt Disney as, "Zorro", from 1957 to 1961. Seeng the swashbuckeling, fencing champ, Guy Williams fall like a clumsy oaf was simply unforgettable!

Another aspect of this scene - the space suits are made of the same bright silver, heavy, material as fire suits. Under the powerful incandesent studio lighting, it was very, very hot on the set. June Lockhart said once everyone was in costume - it was like trying to act inside an oven!

And speaking of ovens - this scene had to be taken in one shot. The man inside the robot suit was being cooked alive every minute he was on camera! 

 

Another Brady Bunch episode is the one where Bobby does an essay on his favorite famous person: Jesse James.
