Oh, how disappointing

Apparently Bill O'Reilly cannot even write factually accurate things about well-known historical events.

That'll teach him to blame the Lincoln assassination on well-known time-traveling-socialistic-civil rights-supporting-Muslim-Obama-lover John Wilkes Clenis.

On the other hand, commentor JKP1000 at Salon appears to have read the book and pulls out what is surely an excerpt:

Lincoln decides he wants to go out for the evening, alright? He asks Mary if there are good movies playing in town. Mary says, "Movies? What?". Lincoln says, "Fuck it! We'll do it live! Let's go over to The Gerald Ford Theatre."

A couple hours later, Lincoln and Mary are sitting in the balcony at the GFT, not bothering anyone, alright? Just as Lincoln starts to relax, some hippie liberal comes bursting in the room behind him waving a pistol saying, "I hate America! I want to tax the rich!". Lincoln says, "Fuck it!" and turns around pulling a derringer from his vest. He aims and fires at the hippie liberal saying, "Take that, pinhead!"
