Raj: I think he’s eating lunch. Uh, Sheldon, I want you to meet Neil deGrasse Tyson from the Hayden Planetarium in New York.
Sheldon: 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.
Dr Tyson: But I actually didn’t demote Pluto. That was a vote of the International Astronomical Union.
Sheldon: If ifs and buts were candy and nuts, we’d all have a merry Christmas. Think about that, Dr. Tyson.
I am going to see Dr. Neil in New Orleans in November. I too will give him a piece of my mind.
