Usually my chemistry jokes get no reaction...seems like they're Boron people to death.
So Argon walks into a bar...and the bar tender says, "We don't serve noble gases here." Argon doesn't react.
Two atoms are walking down the street. The first one says "I've lost my charge." The second one says "Are you sure?" and the first one says "Yes...I'm positive."
But don't trust atoms. They make up everything.
