If you do have something oily like hot smoked salmon, and you don’t want the oils to soak into your nice wood boards (because let’s face it, once the board is out, it doesn’t get cleaned up until after the last guest leaves), you can slap a small plate underneath it to keep the fishy smells out of the wood. And remember, cheeseboards don’t have to be these gigantic cornucopias that can feed the whole neighborhood. Small cheeseboards for two are romantic. Medium cheeseboards for a cozy gathering of close friends work very well without being overwhelming. So don’t go crazy, but… you can go a little crazy.

Yes, but only to a degree. I used to work in radio and there was a “7 second” rule for audio clips. I don’t know if that was how the law defined fair use or our lawyers felt that was the safe zone, but we were allowed to use sound clips from movies and TV so long as they were under seven seconds. You’ll need to do some research on specifics, but in general I suspect you’ll find you can use clips, but they can’t be minute long segments and you’ll probably have to justify their use with commentary on the clip or that the clip highlights.
