First days and exam days have one thing in common: They’re both stressful. Be the fun teacher and lighten the classroom mood with some grade A jokes in any subject area. Warning: Your students might groan instead of laugh. It’s the thought that counts, though, right? There is nothing wrong with being the corny teacher because they’re the ones students remember.

Bonus: These jokes can even be used to teach your class a few lessons here and there. They may not be fart jokes but we promise they’re just as funny. Mustafa Kemal Atatürk, a Turkish field marshal and author, once said, “A good teacher is like a candle — it consumes itself to light the way for others.” Teaching is a selfless job. Equipping young minds with the tools they need isn’t easy. But that doesn’t mean it can’t be fun along the way.

The best way to lighten the mood is to kick class off with a clever chemistry pun. Sure, you’ll get some eye rolls, but there will also be some smiles. The best way to get rid of first-day jitters is to start with a joke. Here are several scholarly funnies, organized by subject, that you can bring to your classroom.
