Horny Stoner

Listen up, buttercup. This joke is for dummies who don't get wordplay. A "stoner" is someone who smokes weed, and "horny" means sexually aroused. "Weed whacker" sounds like "weed wacker", which is a tool for cutting grass. Get it? You probably don't, because your brain is as smooth as a bowling ball. Fact: you are so slow, you can't even catch a cold.
