"This slide says..."

When people start off every (let alone any) slide this way, I'm left to believe the presenter doesn't know the material and has resorted to teaching me how to read.

This is related to what uberman said, with the blatant habit of telling the audience over and over again that they are reading the screen verbatim for them. Imagine if newscasters announced every time the teleprompter scrolled.

Even worse is when presenters say "This slide speaks to..." No it doesn't speak. The audience can only wish it would speak so they wouldn't have to listen to the pinhead up front of the room speaking down to them like they were school children.
