Loved it.
Well, I must say that this is one of the funniest Portal entries I've seen yet. I'm a big fan of the Living in Greytown strip, so I just HAD to see what he had to offer for the Portal. I wasn't disappointed. (The only reason I gave it a 0 for interactivity was... well... it wasn't interactive.) I applaud Dave for his excellent work, and look forward to anything he has in store for us in the future.
