Most tearjerker Rugrats episode?

I’ve seen many episodes of the show Rugrats and there was so many of them that were so beautifully sad and some that provide tears of joy, the one that stuck out for me thus far has been the episode segment Music when Tommy, Chuckie, Phil and Lil tried to teach Dil about music but it doesn’t work because of him in his development stage as a baby, until Didi takes Dil and then sings the song Beautiful Dreamer I think that’s what brought it home because it made me think of my brother and being sure he’s happy. But anyways I’m rambling, if I had an episode that made me cry the most it was that. Do any of you guys have an episode on the show that made you cry the most?
