This may be my favorite dialogue ever:

Brian Schmidt won the 2011 Nobel Prize in Physics for his work on dark energy, and then he took the prize to Fargo to show off to his grandmother. As recounted to Clara Moskowitz at Scientific American the airport security people were a little put off by the way the giant piece of gold sucks up all the x-rays:

"They’re like, ‘Sir, there’s something in your bag.’

I said, ‘Yes, I think it’s this box.’

They said, ‘What’s in the box?’

I said, ‘a large gold medal,’ as one does.

So they opened it up and they said, ‘What’s it made out of?’

I said, ‘gold.’

And they’re like, ‘Uhhhh. Who gave this to you?’

‘The King of Sweden.’

‘Why did he give this to you?’

‘Because I helped discover the expansion rate of the universe was accelerating.’
