Armed with comfortable "black tennis shoes," Sen. Cruz pulled an all-nighter in the U.S. Senate for his "filibuster," advocating the defunding of Obamacare, chatting about White Castle burgers, and reciting Dr. Seuss poetry.

"I do not like green eggs and ham," said Cruz, reciting lines of Dr. Seuss poetry in an effort to take up as much time as possible on the Senate floor.  "I'm a big fan of eating White Castle burgers."

Despite Cruz's strenuous attempts to hold off on the continuing resolution vote in the Senate, it seems Cruz is completely aware that his actions would not have much impact on the Senate's final fiscal decision.

Since Monday, Sen. Cruz had known exactly how long he would be allowed to talk for on the Senate floor, and that his tactics would have no effect except for keeping his promise to use "every procedural tool" to slow down Obamacare.

This is because Cruz discussed the terms of his "filibuster" privately with Majority Leader Harry Reid, who allowed Cruz to speak when there were no objections from other Senators.

With the Obamacare bill vote looming, and the fiscal fate of America hanging in the balance, Cruz's filibuster vendetta has teeth grinding on both sides of the political spectrum.

"If the House doesn't get what we send over there until Monday, they're in a pretty tough spot," said Minority Leader Mitch McConnell, a Republican senator. "I'd hate to put them in a tough spot."

Majority Leader Sen. Reid called Cruz's 21 hour speech a "big waste of time." 

"With all due respect, I'm not sure we learned anything new," said Reid.
