So yesterday I shared a joke about science with some of my students, it went like this:

So a Neutron walks into a bar and asks the bartender, a Proton, "How much for a beer?" The bartender says, " for you, no charge." The Neutron says, "Are you sure?" And the Proton bartender says, "I'm positive!"

So my nerdy colleagues and my students have a good laugh, and then one of the kids says, "I have a science joke", to which we all reply, "Ok, let's hear it", and she replies, "Creationism!" The place erupts!

Never say the kids don't know. It was awesome!
