Pretty much anytime there's a video involving a marriage proposal, it will fall under this and Crowning Moment of Funny.
One early clip had two little girls sitting at a table eating pizza. One of the girls ate the other's slice and was caught, the other girl bursting into tears. Instead of the slugfests that usually happen on the show, the first girl actually apologizes, then offers her pizza instead. The other girl cries out that she's sorry and hugs the first girl, quickly making up.
