As a nuclear scientist, I’m familiar with chain reactions and have made a career of harnessing and controlling them.
If not enough atoms get excited, the reaction dies out.
If too many get excited, the reaction gets out of control and…
Well, let’s just say the least of it is that I lose my job.
Not that I’m worried about that. I’m really good with chain reactions.
Well, usually good.
However, when it comes to nervous reactions, I’m completely hopeless.
One person in a crowd gets excited.
Then two.
Then ten.
Then twenty.
I guess shouting “RADIATION LEAK!” doesn’t help.
