Raj Koothrappali : Sheldon, I want you to meet Neil deGrasse Tyson from the Hayden Planetarium in New York.
Sheldon Cooper : I'm quite familiar with Dr. Tyson. He's responsible for the demotion of Pluto from planetary status. I liked Pluto. Ergo, I do not like you.
Neil deGrasse Tyson : But I actually didn't demote Pluto. That was a vote of the International Astronomical Union.
Sheldon Cooper : If ifs and buts were candy and nuts we'd all have a Merry Christmas. Think about that, Dr. Tyson.
