Astrophysicist joined Thursday, where he was stunned by some little-known knowledge: just like Groot, and of course Baby Groot from is not an animal, but a living plant.
“Oh, by the way,” said deGrasse Tyson, “did you know that ET was a sentient plant, not an animal?” “ET is a plant?” Colbert responded. “Turn on your heart light. He’s got a heart.” “Well, okay,” deGrasse Tyson replied, “so they gave it a heart so you can identify with it. But it was a plant.”
According to deGrasse Tyson, he got this information from a fairly reliable source.
“How do you know it’s a plant?” asked Colbert. “Remember when ET would touch the plants and they would grow back?” asked deGrasse Tyson. “That’s not an accident.” When asked how he knows, deGrasse Tyson replied, “told me in my office.”
Viewers didn’t know what to think.
What started the conversation about ET in the first place was a long and animated diatribe from deGrasse Tyson about the possibility of aliens that are in fact living plants, and what they would think if they saw the vegetation created by humans on earth is consumed. This left Colbert with only one question.
“To get to that idea of the plants in question,” Colbert said, “did you smoke baby plants?”
