It's your favorite time of the week! That's right, time to open up the knowledge vault, dig to the bottom and find facts that amaze, amuse, or entertain! (Don't forget to check out number 4).

1. We say "o'clock" because way back in the 13th to the 17th century, clocks were a rarity.  So when someone was telling you the time from a clock and not a sundial or just guessing, they'd say, "It's four of the clock."  And that became "o'clock".

2. There's no expiration date on honey . . . it's the only food that can actually last forever.

3. Only one NFL quarterback has ever thrown a touchdown pass to himself.  Former Minnesota Vikings quarterback, Brad Johnson, threw a pass in 1997, a player on the Carolina Panthers deflected it.  That's when Johnson grabbed it and took it in for a touchdown!

4. British spies used semen as invisible ink. They stopped because it began to smell like it wasn’t fresh.

5. If you could see the entire universe, it would look like a light beige color.

6. Did you ever feel that Hollywood was unimaginative? You are right! Only 25% of the major Hollywood movies this year are totally original . In 1984, it was almost 59%.

7. Sometimes animals are underestimate. Case in point: Robert Biggs, an elderly hiker, was watching a mama bear and her cub playing in a stream when a mountain lion suddenly attacked him. The bear heard the commotion, rushed to the hiker's aid and attacked the big cat. The bear then calmly went back to its cub. Biggs is fine.

8. Here's a word that is actually real but not in use these days: floby-mobly. It means not feeling unwell, but not being at your best either.

9. Tigers share food from a kill with their streak (group) while lions will fight their pride to the death for the kill.
