I loved it!
Brilliant style... what a huge damn improvement from #3! I loved the way Blockhead is just so carelessly random, but I can tell that to make it funny you've clearly thought about it! I have to ask - did you use any .gifs at all in that for backgrounds and stuff? I could see you'd drawn the wood (it was really wood-like!), but like at the beginning the psychiatrist's from outside?
Anyway great work... I'll put it on my faves, and although they need sortin' out - this will definitely stay!
