It's Slater from Dazed & Confused!

"Slater-san, how's it goin'?"
"Fixin' to be a lot better, man!"

"George Washington was in a cult, and the cult was into aliens, man."

"Didja ever look at a dollar bill, man? There's some spooky shit goin' on there. And it's green too."

"Behind every good man there is a woman, and that woman was Martha Washington, man, and everyday George would come home, she would have a big fat bowl waiting for him, man, when he come in the door, man, she was a hip, hip, hip lady, man."
