I just discovered the coolest web site (well, “cool” may be relative in my case). But writers and grammar geeks everywhere will enjoy Grammar Rules, which offers products for the “grammatically aware lifestyle.” It may sound a little odd (except to people like me, perhaps) but the products are so well done — a combination of coffee-shop simplicity and typewriter artsy — that they’re rather irresistible, even if you already know your linking verbs from your gerunds.
In addition to the plates and mugs, you can buy greeting cards that cover everything from verb tense (“Today we do it. Friday we did it. We have done it often.”) to direct objects to contractions.
Now, I shop. Tomorrow, I will be poorer.
