Episodes you actually get emotional over..

[EMCE Hammer]

Final episode of MASH gets me...
The episode where Henry Blake dies is up there too.

Andy Griffith episode where Andy gives Opie the talk about killing the mama bird with a sling shot.

The two Mash episodes you mentioned, Archie Bunker's Place when Edith dies, and the finale of Barney Miller come to mind for me.

^Finally!!! Another Walton's fan here. Worth so much more than custom fodder ;-) If you don't cry when Grandma comes back after her (real-life) stroke, you're dead inside.

Wow, all these and believe it or not, the Waltons. Almost all of the episodes have moments like this and take you from the Great Depression through WWII. Great history lesson and pulls you in like a first person experience. I watched them all with my wife a few years back and was a fan pretty quickly. Brother can you spare a dime? No wonder it won Grammies. Allot of the people (the greatest generation) were our ages when it originally aired.

In Spongebob when the Flying Dutchman tells Spongebob and Patrick they have three wishes and Spongebob wishes that Squidward was there with them.

[Sideshow Spock]

For me with Star Trek, it's Devil in the Dark when Spock is melded with the Horta and communicating for her. There's "something in my eye" every time.

Dr. Corey's self-realization and Christine's loss is also very poignant IMO in "What are Little Girls Made Of?"

Many films affect me thusly, but I can't think of any sitcoms that did. Maybe when Edith died on All in the Family.

Star Trek...The City On the Edge of Forever.

At the end, Kirk's reaction to Edith Keeler's death.

The Lost in Space episode The Time Merchant.

For 3 years Doctor Smith has been a total butthole throughout the years.

He would never raise a finger to help anyone and would quickly sell everyone out if it would get him back to Earth.

In The Time Mechant he is finally back on Earth but the cost will be everyone in the Jupiter 2 will die.

In a stunning moment clarity Smith yells --- NO --- I CAN'T DO IT !!!

He is then Lost in Space again with his now saved pals.

Being a huge LIS fan that scene always gave me a lump in my throat

[Brown Bear]

Couldn't agree more about Happy Days. When Ritchie tells Fonz he wrote him a letter....gets me every time

[Spawn67]

We all know that T.V. sit coms aren't real life but is there ever a episode or episodes you get emotional over?

For me it's the Happy Days episode where richie says goodbye...

That and the "Memories" sequence from the final Happy Days show right before the wedding (tried to find it on youtube but I guess they took it down)
