Watch Greta Thunberg rickroll the world

At yesterday's Climate Live concert in Stockholm, Greta Thunberg took the stage to massive applause before stating: "We're no strangers to love." And with that, the rickroll began.

"At the end of the day, we are just teenagers fooling around with each other, not just the angry kids the media often portrays us as," Thunberg told Swedish newspaper Aftonbladet.
