One of which is to not take the suggestion literally.
If someone suggests banana, please do not eat a banana. If someone suggestions bathroom, do not take a mimed dump onstage. I'd forgotten the impulses to jump from one word immediately to the first thing I think of: that's what the audience does. When they say cake, they think in their heads "Oh my gosh, I love cake. I wish I was eating cake." But they don't really want to see a scene with a character who has a train of thought like that. You've gotta be one step ahead of your audience.
