Definitely the episodes Joker's Favour and Eternal Youth stand out. Whenever I think of TAS the images of all the 'woodened' people and Harley jumping out of the cake are the first to pop into my head. 
But there were sooo many memorial moments. Like the first Scarecrow episode with the fight above the stadium. 

I think finding a list of episodes that I didn't like would be way easier than the ones I did like, oh wait, there isn't an episode that I don't like....  Ah well.  One of my personal favorites is actually Robin's Reckoning which I was SHOCKED to see didn't make it on his list, not even his runner-ups.  I also throughly enjoy Riddler's Reform.  The subtle clues Riddler leaves are perfect and Batman disappearing with lightning is legit. 

1. Heart of Ice
2. Harley and Ivey
3. Two-Face Parts 1 and 2
4. House & Garden
5. Harley's Holiday
6. Mad Love
7. Harlequinade
8. If You're So Smart, Why Aren't You Rich?
9. Tyger Tyger
10. Mad As A Hatter
11. Feat of Clay Parts 1 and 2

Great watch....ahhhh...memories
 
The one with Rupert Thorne and his brother was amazing, where his brother was a priest that saved him from an oncoming train when they were young or something to that affect

I never even knew about Baby Doll until that list. Needless to say, I want to see the ep. >___>

I Am The Night, Perchance To Dream and Heart Of Ice could all be number one. These three episodes are in a league of their own in my opinion, not just in the Batman series but all comic book animated series.

it says a lot about this show that people can argue what the top episodes are. Great stuff.

One was a perfect pick, but two was overrated I found Baby Doll pretty annoying.
