KEVIN O'LEARY: I USED TO THINK TESLA WAS A JOKE

"A few years ago, my son, who is an electrical engineer, was interning at Tesla. 

'Dad, why don't you own some Tesla? I work there as an intern.'

I said, 'I wanna short that stock. It's such a joke. It's a car company trading at a ridiculous price.'

He said, 'No, You're the joke.'

So, I took my phone out, and I bought a whack of the stock in my personal account, and I forgot about it. 

One day I opened up the thing and I was up a 1000%."
