>>90642023I was gonna say basically the same thing as
>>90642369, with the additional note that the "kind of weak" possibility for the third one is actually the second half of a paired set that makes a BIT more sense when grouped with the first one it aired with (but is still kinda blah itself, true.)
If you're interested enough to try to look for what I think are better episodes, then maybe try "Mewberty" (THAT one you won't forget!), "Mewnipendence Day," "Game of Flags," or "Running With Scissors" (THAT one you won't forget, either!).
Those are just off the top of my head and I have no doubt that anons will contest them, but I'll say that what I consider the top tier is populated exclusively with plot-heavy episodes (example: all of the last five quarter-hours of Season 2,) that I wouldn't recommend you start with, so none of those are what I listed.
