1. Welcome collaboration, but make sure the ideas resonate with your vision.
2. Do takes that are faster. It's always slower when you watch it back. Faster is funnier.
3. Make sure the actors are comfortable doing less.
4. Do as much as you can in single shots. Cutting to different angles makes it less funny.
5. Have really old people in the background and out of focus. Don't know why, but it's funny.
6. Use funny names.
7. Keep to the page.
8. Ignore the page.
9. In drama, your characters sit and talk. In comedy your characters can't talk because one is deaf and the other is trapped under the sofa.
10. Don't be too topical. Good humour lasts forever, but a joke about George Bush is an embarrassment, much like his foreign policy.
