I missed this episode recently but was able to see through "other sources".
Things I liked about the episode:
Bloo running around like Daffy when he was let out of Mac's school bag
Wilt as the flag pole
Madam Foster tricking Moose and giving Lil" Lincoln what for.
Things I didn't like:
The way Mac's teacher threw The IFs in the closet. I've had teachers like that and I always got P.O.ed whenever they tore up comic books and what not in front of the students.
I didn't go into this expecting a Mac/Frankie thing. If that happens it will be in its own good time and not before.
