It'll be cool to see how each of your treatments of the material end up. Man I love the fan editing community!
I'm no editor, but TF2 felt far more like a "workprint" to me than the first movie, like if you just trimmed a lot of the stuff it would be a watchable movie (though still a "dumb popcorn movie" in the end).
So yeah, sorry about that. I didn't think the masturbation scene worked for me, but my friend (who is twenty years older than me) thought it was a laugh riot. It's like the last possible thing they could be talking about/doing showing the mom is completely clueless (and Sam has no dignity left). Some of those jokes work a little the first time you see it to get a few cheap laughs from the audience, but just don't hold up well on repeated viewings.
