Part of the acting gig is when you're let loose some improvs and put stuff into your own words every once in a while. That doesn't get you a writing credit or more money. It just makes it more fun.
Jack BlackI don't think of myself as a great improver. A lot of times there's long periods of silence when everyone in the recording studio is looking at their watch and waiting for me to say something. And I'm searching desperately in my brain for anything before something dribbles out.
Jack BlackI just had a son and had to take him to the paediatrician and he measured his head and apparently he's in a group in which only 14 per cent of the population have a bigger head than him. Then she said: "Do you mind if I measure your head?" I said: "Go ahead." And she was shocked, because less than one per cent of the world's population has a bigger head than mine. So I guess that means I'm pretty full of myself. Or that I have a huge brain.
