Two friends attempt to climb a skyscraper's stairs to see how long it takes. They reach the 70th and 80th floors while dealing with muscle pain and fatigue, mixing encouragement with humor as the challenge wears on.

How long does it take to walk up one of the tallest buildings in the world?
Starting with this first step, Casey and I are going to find out. Honestly, this is like a walk in the park. We just hit the 6th floor.
I feel great. This is easy. Look at this little sprintiness step. Now we're talking. Third of the way. Why is walking upstairs so hard?
I'm feeling muscles I didn't know I had.
All right, only 50 more floors, Jimmy. Oh God.
He's doing great.
Uh-huh. I regret this. How you feeling? I'm not feeling good.
Number 70. The grind continues. Floor 80, feeling strong. And after 6 more floors, oh my. Oh my gosh. Look how much more we have to climb.
Oh, that's not bad. Ah, hold on. You got it, Jim. We're almost there, Jim. Keep going.
This is the easiest thing I've ever done. There's one more floor. Oh, why is this so steep? Come on, Jimmy! We walked this high up? Oh! I'm gonna take a nap.
