Hah! Saw this one - quite amusing. Act II was my favorite. Act III starts out great, but I thought it fizzled at the end.

Yeah. I thought about it a bit, and it'd been really hard to pull off an actual ending if they hadn't ended it the way they did.

So many great lines in this one though. Will have to get the DVD if they go that route.

These are not the Hammer...............The Hammer is my Penis.

Captain Hammer, Corporate Tool.

How are things with cheesy on the outside?

It's curtains for you...lacy, gently wafting curtains.

I'm moist. At my most badass I make people feel like they want to take a shower.

And sometimes there’s a third even deeper level. And that one is the same as the top surface one… Like with pie.
