A band of senators had a reunion tour of sorts Wednesday night.

Sens. Mike Lee (R-Utah), Rand Paul (R-Ky.) and Ted Cruz (R-Texas) all spoke on the Senate floor as part of Paul's marathon, 10.5 hour floor speech against a renewal of the Patriot Act.

The men, you may recall, all spoke during very long speeches Paul and Cruz gave in 2013; Paul spoke against the use of drones and Cruz against Obamacare.

"I'm reminded of the movie 'The Blues Brothers,'" Cruz said late Wednesday night. "Jake, we've got to get the band back together again."

It appears that Cruz's quote wasn't exact. But he seemed excited. And ready to relive the glory days. You know, back when Cruz and Paul weren't battling one another for the 2016 Republican presidential nomination.

The Texas Republican reminisced that the first time he spoke on the Senate floor was during Paul's filibuster on drones.

"I will go to my grave in debt to Sen. Rand Paul," he said.

The two men have also exchanged tips, because very few people know how best to survive an hours-long speech where you can't leave the floor to eat or go to the bathroom. Paul did not wear sneakers during his first filibuster, and suggested Cruz do so. The cowboy-boot wearing Texan said he reluctantly bought a pair of kicks for the occasion. Paul changed from wingtips to sneakers on the Senate floor Wednesday.

"I have no doubt his calves and thighs will thank him in the morning," Cruz said. Or maybe not.

"Even with better shoes my feet still hurt," Paul said after his speech.

The Texas Republican said his colleague from Kentucky gave the pro tip of not drinking too much water before and during the long speech. Apparently Paul didn't take his own advice last time. This go around was different.

"I didn’t drink any water," Paul said after the speech. "I’m really thirsty right now. I should have gotten some water when I finished."
