"While many teachers might doubt this, the teaching of grammar is not rocket science!" —Phyllis C. Hutson, The Essentials of Grammar Instruction, 2006, p. 1
So many terrible jokes could come of this...But grammar is such a gas! Really, so potent it could be rocket fuel!
Instead, though, we will refer you to the hilarious book Not Rocket Science, by our beloved friend Craig Conley. It's the world's only compendium of things that are not, in fact, rocket science--and it's infinitely more amusing than our lame puns.
