Stewart was so taken aback on Tuesday's "The Daily Show" by Reid's defense of Adelson, who spent $90 million on Republican candidates in the 2012 presidential election, that Jason Jones had to break it down for him.
"Isn't it hypocritical for Harry Reid to draw a distinction between Sheldon Adelson's money and the Koch brothers?" Stewart asked.
Jones said the answer was pretty self-evident -- Adelson's money and power in Reid's home state helps the senator, while the Koch brother's dollars do not.
"So what is corruption?" Stewart asked.
"Corruption is a billionaire who spends their money on sh*t you don't like," Jones said, and free speech is "a billionaire who spends money on sh*t you do like."
