Chidi: I'm sorry, but this is an important moment in our friendship...
Michael: [cycling] On your right, mate!
Chidi: Oh, jeez. Watch it, man! [A/C unit crashes] Oh, my God.
Uzo: Are you okay?
Chidi: That... That is right where I was standing. I was frozen here, unable to make a simple decision, and I almost got crushed by an air conditioner. This is a sign. I shouldn't be using air conditioners. The freon is awful for the environment.
Uzo: That's the lesson you take from this? Chidi, your brain is broken. You need to fix your brain.
