Finally!

Thing 5: Melilot, do you know William...William...[I wait, figuring she's going to ask me about a student, but I couldn't remember having one named William] William...William the...the...William...
Me: William the Conqueror?
Thing 5, astounded: Yes! Who is he?
Me: Conquered England, Norman Invasion, all that.
Thing 5: How did you know?!
Me: Battle of Hastings, 1066.
Thing 5: Yes!
Me: Came over from Normandy defeated Harold, the last Anglo-Saxon king. I read a book on him, Harold, actually, and one on William the Conqueror's wife, Matilda.
Thing 5: What?! Why?
Me: Because they were interesting.
Thing 5: Are there pictures of him? Of William?
Me: Depends on what you mean by pictures. There's the Bayeux tapestry, which is one of the biggest history sources of that time, recounting the entire battle. It's huge, taking up...
Angie: Why are we still having a history lesson?
Me [overly excited]: Because I love it! For once we're not talking about kombucha or recipes or something like that. This is my turn!
