I tend to underrate this episode a lot, I think possibly due to just how unpreposessing the premise is, but reading you guys talk about it does serve to remind me how well the team did turning that simplicity into the episode's greatest virtue. Freed from concerns such as plot development, the writers let the characterisation drive this episode, allowing them to have a lot of fun with Mac and Bloo's personalities as well as reinforcing their relationship as best buds.
I agree with Mr Marshmallow's picks for top scenes, too; their frantic last-gasp efforts to do something awesome in the final two minutes are hilarious, just because their attempts to have fun become so self-defeatingly stressful. The delivery of "THIS IS BORING!!" and "I KNOW!!" cracks me up because of the tone of stark terror and horrified realisation in their screams.
And I empathise - goofing off is a serious business.
Edit - Ooh, yeah, 50th post!! I am a n00b no longer; after four months, I have finally attained "Settling In"!!

Man, I need to post more...
