What can you tell me about the Tonight Show with Jimmy Fallon? 
Well, I know that it comes on really late at night and the show was originally hosted by Johnny Carson. I don't know much other than that! Do you watch the show?
Yeah sometimes. The Tonight Show with Johnny Carson played from 1962 to 1992. 
Who took over after Johnny Carson? I think there was someone before Jimmy Fallon?
The Tonight Show was hosted by Jay Leno after Carson.  The show has been on the air since 1954.
