What's the worst public speaking advice you've ever been given?

I posed this question on The Eloquent Woman on Facebook, and it took almost no time for a gang of readers to agree that the advice to picture the audience naked was their pick for worst speaking advice ever.  (Even so, I Can See You Nakedis one of the best-selling presentation books ever.)

But there were a couple of other nominees: Bobbi Newman voted for the advice "that feedback forms are important and useful" and Claire Duffy offered, "From my 5th grade teacher: 'To quell nerves let your eyes float above their heads'. Even then I knew it was stupid."

If you've had some other awful public speaking advice that did not stand the test of time (or even the first try), share it in the comments.
