I may have not seen all the episodes, but I have seen a few to put up my top 5. I know it's not the top 10, but it's better than nothing.
1. Frankie My Dear - I don't have to say why,
except that this is what got me into the show!
2. Setting A President - Another triumph for Frankie. She would make a great political leader.
3. Bloooo - I loved the Ghostbusters reference. That was great.
I also loved Bloo's conversation on the mirror.
4. The Big Lablooski - Mac's quip 'Now who's weak?' had me going for a while, until the paddle ball guy showed up!
5. Cookie Dough - just because of Bloo destroying the kitchen.
His expression was funny!
