Top three favourite episodes?

What is your top 3 favourite episodes in the whole series? For me it's the following:

1: Ted, just admit it. I love Casper casually ragebaiting red and the interactions between the two

2: The Ex stops by. I think it was a good first introduction to Ex whilst keeping her origin a mystery

3: Three Sisters. I mostly love Casper's idgf attitude (and him ignoring the mucklewains was also pretty funny)
