Some more from Douglas Adams quotes:

• It is a mistake to think you can solve any major problems just with potatoes.
• Humans are not proud of their ancestors, and rarely invite them round to dinner
• Anyone who is capable of getting themselves made President should on no account be allowed to do the job.
• For a moment, nothing happened.Then, after a second or so, nothing continued to happen.
• I don't believe it. Prove it to me and I still won't believe it.
• Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the drug store, but that's just peanuts to space.
