Herkabe's comments about Einstein -- that he carried "spare pants" until he was 24, but he didn't let that bother him and eventually went on to build the first nuclear bomb -- are absolutely false. Einstein was quite suave and a ladies man when young (not your typical "nerd"), and neither Einstein nor his theories had anything to do with nuclear physics -- this is a very common misconception, but anyone who knows anything about Einstein and the history of the A-bomb knows it is not true. Herkabe being so educated should have known better.

Reese: But thats not fair.
Lois: I WILL BLAME YOU!
Cold Open: Dewey pretends to have a tea party to get Hal to buy him something he's wanted.
