Epic!
Not only entertaining, not only well drawn and animated, not only perfectly timed and synched, not only hilarious, but really, really long. VERY EXCELLENT!
I give you the highest possible score -- not just for your fine work, but for not cheaping out and for doing the Whole Damn Song. What a great and rare piece of work you have produced!
Your flash has reaffirmed my belief in the Portal, gotten me my ham radio license, taught me to divide by zero, and given me the strength to watch several more new submissions. Thanks!
