If you've watched Comedy Central's hilarious and informative Drunk History, then you know learning about American history doesn't have to be boring. It's hard not to laugh when Jenny Slate, Natasha Leggero, and others do a bit of drunken (read: hammered) storytelling while the likes of Bill Hader and Kristen Wiig pantomime every single word that comes out of their mouths.

Now that Drunk History is back with all-new episodes—and especially since it's Fourth of July weekend—let's take a look at some of the most important (and amusing) facts we learned from watching the show's first season.

1. Al Capone had a slightly below average IQ of 95.

  

He contracted syphilis when he was about 18 years old.

Capone could have solved his syphilis problem, but he didn't tell anybody about it until after he was arrested. It ended up causing enough brain damage to give him the mental capability of a 12-year-old.

2. Coca-Cola, America's favorite soft drink, was originally manufactured with excessive doses of cocaine.

They still use the same coca leaves in Coca-Cola's recipe, but extract the cocaine, which begs the question: What happens to all of that extra cocaine?

3. It's no secret that J. Edgar Hoover was one of the shadiest figures in the U.S. government.

The FBI harassed Martin Luther King, Jr. after he met with Hoover, and blackmailed him with a tape of all of MLK's trysts with other women.

4. Chris Romano had no idea he'd been placed in the Witness Protection Program until he was 14 years old. His mother sat him down to tell him the truth:

In the 1970s, his father, Johnny Cool (née Shaheen) was one of the biggest arsonists in Massachusetts.

He struck up a deal with the authorities and was placed in the Witness Protection Program.

5. When Patty Hearst, granddaughter of media mogul William Randolph Hearst, was kidnapped, she surprised the world by being totally cool with her captors. 

She worked with them to extort her family.

And robbed banks.

She looked pretty great while committing these atrocities, too.

6. The Kellogg brothers had a major falling out over the invention of corn flakes.

They sued each other back and forth.

 

7. Lewis & Clark may have had the sweetest bromance in American history.

Also, nearly everyone on their expedition contracted STDs.

8. The Scopes Monkey trial resulted in one of the most important rulings for the American education system.

It was also the first time Americans were able to listen to a trial on national radio.

9. Everybody knows Billy the Kid was a badass, but apparently he also had a unique singing voice.

He spoke Spanish, too.

10. John Wilkes Booth had major daddy issues. His father refused to be photographed with him.

This prompted a sibling rivalry with his brother, Edwin Booth. Eventually, they reconciled as adults and appeared on stage together in Julius Caesar. 

He changed his original plan from kidnapping Abraham Lincoln to assassinating him after discovering that he would be attending a performance of Our American Cousin.
