Lions vs. It

Tonight as we're loading up the car leaving church my darling husband, who is driving separately, says to Charlie, why don't you tell Mama about the lions! And promptly shuts the door.
Please keep in mind at this point I've:
Awoke with the chickens, opened the school, worked all day, brought Jack home from daycare, chased him around, packed dinner, drove back across town, went to church, chased other people's kids around. I just wanted to turn on the magical DVD player and zone out for the 30 minute drive home.
I digress, the lions.
Charlie informs me he has checked out a new "chapter book" (his phrase, not mine) about lions. Then he launches into a 30 minute (I kid you not) dissertation about lions.
Mama, did you know lions eat food with BLOOD in it? You know why? They can't cook their food because they don't have kitchens so they have to just eat the blood with the meat.
If the zebra ate a chicken before the lion caught it, then the lion gets to eat the bloody zebra and the chicken! (uhhhh....ok)
Mama, did you know only two boy lions are allowed in the Pride? A pride is a family of lions, but the only boys are the lion king and the uncle, the rest are "lady lions". The other boy lions have to fight to be the king and if he wins he eats the babies because he only wants his own baby cubs, they're called cubs mom, that's what they're called (holy crap....)
He proceeds to tell me about how baby cubs like to snuggle with their moms, they are good jumpers, they like eating meat and blood (we covered that several times....) about their teeth, claws, sleeping habits, on...and on...and on.....
I ask him "Charlie, how do you know all of this? Did the teacher read you this book?" No.
"How do you know so much about lions?"
Mooom... I read the book myself when I looked at the pictures, that's how I know about the blood. And the rest I learned on Wild Kratts (yeah PBS!) Papa told me that lions don't have kitchens, and the rest I figured out on my own.
Whew. After all of this can someone please tell me why my kid can't remember the word "it" on his flashcards, but is practically the lion whisperer. Someone, anyone?
