There are many misunderstandings in the first story. The story is a basic problem that becomes complex with Bloo lending a hand to help fix the problem. But isn't that always the case? It is funny though, but it is always funny when he suffers the consequences of his actions.
The second story also involves Bloo helping out and messing up, providing unusual circumstances. The story has filler though, what with the exercise that Mac has to preform in order to get to the end of the story. Unfortunately, that isn't all that funny, so I wish something else happened.
