For those living under a rock, or in the southern Arabian peninsula — under Iraq (ha ha ha!) — the pun is a form of humor that dates back to Egyptian hieroglyphics. If English is not your first language, or you have an impaired sense of humor, let me explain the title of this post. You see, cranks are what connect the pedal to the bike. And because riding a bike is good for one’s mood, being cranky is both ironic and a pun about that. Because if I can’t use my bicycle, I become grumpy. Having to explain a joke is a sure sign it’s not that funny. However, it’s still a pun. But if you got a chuckle or not, keep reading.
