Why conservatives have a reputation for not being funny

ShopNetDaily | Help! Mom! There Are Liberals Under My Bed!
"Help! Mom! There Are Liberals Under My Bed! A Small Lesson in Conservatism" is a wonderful way to teach young children the valuable lessons of conservatism. In simple text, parents and children follow Tommy and Lou on their quest to earn money for a swing set their parents cannot afford. As their dream gets stuck in Liberaland, Tommy and Lou’s lemonade stand is hit with many obstacles.

Liberals keep appearing from behind their lemon tree, taking half of their money in taxes, forbidding them to hang a picture of Jesus atop their stand, and making them give broccoli with each glass sold.

There's also a link to Conservatives Are From Mars (Liberals Are From San Francisco), an actual funny title that someone should jack up and put a better book under it. Featuring a "buy this book" blurb from well-known humorist William Peter Blatty.
