Grammar Funnies

Here are some grammar funnies I want to save:

The Writer's Den:  "Grammar," quoting a piece in Physics Review Letters, of all things, in 1979! Ancient history! (And the year I went to college.)

My favorites:

12. Don't use commas, which are not necessary.
18. As far as incomplete constructions, they are wrong.
20. In my opinion, I think that an author when he is writing should definitely not get into the habit of making use of too many unnecessary words that he does not really need in order to put his message across.
21. Use parallel construction not only to be concise but also clarify.
22. It behooves us all to avoid archaic expressions.
23. Mixed metaphors are a pain in the neck and ought to be weeded out.
26. Last but not least, lay off cliches.
