Though not the best of the series...
It gives the best example of BH's behaivior. I'm not so easily amused, but something about the contradiction of a childish idiot and a wise-ass concience makes for comical dialogue.
Another thing I liked was your not trying to cram in an entire story into the average 5 minute flash length - just plop Blockhead down in any setting and let him and the concience duke it out.
And the match begins. Huzah.
