What are the moments that bring tears to your eyes and/or a smile in a good way?

No tears but when Lucy tells Ricky she's pregnant on I Love Lucy. Ross and Rachel finally get together during Season 2 of Friends. Thats all I can think of right now.

I have been watching the original Lassie. On the very last episode with Jan Clayton and Tom Rettig, Ellen and Jeff leave their home for Gramps has died and they can no longer manage the farm. Jeff calls Lassie to get in the car, but sees little Timmy is sad. He goes over to Timmy and says " You can have Lassie now". I had that as a warm and fuzzy moment.

The I love Lucy Christmas episode looking back when Lucy tells Ricky she's expecting and later when they practiced for the big moment.

On CHIPS when a baby was abandoned at a truck stop. Ponch took a liking to her and wouldn't put her down or let anyone else hold her. It was so cute!

I second you on that one, but there's another Tear-Jerker when the dawg switches owners in season 11.

For this episode, it cuts both ways, sad to see Timmy go, but glad she goes to the Ranger (Whom you first saw in Season 10).

I have to add the end of The Golden Girls - "I love you, always". "You'll always be my sisters, always".

when Sheldon told Amy on BBT that he loved her...I was like yesssss...awwwwwwww:)

On the very last show featuring Lucy/Ricky/Ethel/Fred (The Lucy-Desi Comedy Hour). Edie Adams sings a beautiful version of That's All. What makes this so poignant is that Lucy and Desi were divorcing at the time, and Edie said that during rehearsals , Lucy would burst into tears when she sang the song.
