Discovered Frasier in 2010 (I was 15). Loved it ever since and will always keep loving it. Most of these are pretty Niles/Daphne centric, but I didn't include the major ones. One day, I swear, I will make an entire list of all the episodes.
I'm always surprised by how few people include the pilot episode, which won Emmy awards for writing, directing and acting (Grammer). It's a laugh riot and does a great job introducing the characters. I judge episodes by how many actual LOLs they get out of me.
