Sen. Ted Cruz, R-Texas, spoke on the Senate floor denouncing Obamacare for 21 hours and 19 minutes. To fill that time, and probably to keep himself entertained, the senator got creative.

Here are the 10 strangest references Cruz made during his filibuster-that’s-not-technically-a-filibuster:

1. "Green Eggs and Ham"

Foxes, houses, cars and good old Sam. Cruz read the story to his daughters, since he couldn’t be there in person to tell them goodnight. Awwww!

2. "Duck Dynasty"

"Si also said, ‘your beard’s so stupid it takes two hours to watch 60 Minutes.’ "

3. "The Little Engine that Could"

"You know, I have to say, if you listen to a lot of members of this body, the message would be simple: ‘That little engine can’t.’”

4. Toby Keith

"I will not endeavor to sing, because even though it might not violate the Senate rules, it would violate rules of musical harmony, human decency and possibly even the Geneva Convention.”

5. Wrestling

"You know, it's a little bit like the World Wrestling Federation. It’s wrestling matches where it’s all rigged [and] the outcome is predetermined."

6. The moon

"The moon might be as intimidating as Obamacare."

7. Nazis

"Look, we saw in Britain, Neville Chamberlain, who told the British people, 'accept the Nazis. Yes, they'll dominate the continent of Europe but that's not our problem. Let's appease them. Why? Because it can't be done. We can't possibly stand against them.'"

8. Ashton Kutcher

"I salute [Ashton Kutcher] for carrying a message to young people about hard work and diligence and working toward the American dream.”

9. Darth Vader

In crude Darth Vader voice: “Mike Lee, I am your father.”

10. Ayn Rand

"In the last three years, my understanding is the sales of ‘Atlas Shrugged’ have exploded because we are living in the days of Ayn Rand."

Okay, maybe Ayn Rand isn’t that far of stretch for a conservative, but reading “Atlas Shrugged” on the Senate floor is no less strange.
