As English teachers, it is difficult not to be a stickler about grammar. These rules, provided by the Creative Teaching website (which is cool in and of itself...check it out), are hilarious!
Humorous Grammar RulesGive these rules as a list for students and when issues with one or more of these rules come up, refer students back to the list for some practice and to get a good laugh! Also, you can use these rules for a rule of the week type of thing. A bulletin board would also be a neat idea.
