One liners to use for a presentation

Starting off a new thread here are a couple of one liners that you could use in a presentation

"It takes 3 weeks to prepare a good off the cuff speech" - Mark Twain

Winston Churchill said that "it takes me all of 10 minutes to prepare a two-hour speech, but takes two hours to prepare a 10 minute one"

Interestingly his maiden speech took six weeks to prepare and was completely memorized.

If you see any interesting quotes add them in here.

I saw a great one liner delivered by Fons Trompenaars at the Marketing Forum.

After walking up on stage he received a polite round of applause. He replied by saying "Thank you for the applause, it is so nice to get it at the beginning - as I seldom do at the end.." The audience roared with laughter.

How about these?
