You'll be using one of the leading textbooks in the field - I wrote the thing and need the royalties.

If you follow these few simple rules, you'll do fine in this course - Providing, of course, you don't need any sleep or other 'life.'

The gist of what the author is saying is what's most important - I don't understand this at all either.

Today we are going to discuss a most important topic - Today we are going to discuss my dissertation.

I haven't time to consider all the people who made contributions to this field - I disagree with what roughly half of the people in this field have said.

The test scores were generally good - Some of you managed a C+

The test scores were a little below my expectations - Where was the party last night? (and/or) Did any of you idiots even bother to study?

Some of you could have done better - Everyone flunked.

Before we begin today, are there any questions about previous material? - Has anyone bothered to open the book yet?

According to my sources... - According to the guy who taught this thing last year...

It's been very rewarding to teach this class - I hope they find some other sucker to teach this turkey next year!
