DAVID J. MALAN: Hello, world, this is CS50 Live. Heh, heh. So if you see me trip, if you see me misspeak, if you see me screw up-- all of that is happening literally right now in Cambridge, Massachusetts. Oh, hi, world. 

Drum roll. 

Perspec-- yeah, per second. 

Pause the vizeo, if you'd like. 

Look redder. Ha. Ha. 

A-BUT-DUNE will just giz Mark Zuckerberg's favorite patent-- to protect our nuclear missile.

Bugle itself ga-oggles. 

Good epi-sude for you. 

It's awk-tually quite fine, uh, ends an you may rave recall, head to this you are here. This is CS-fic-pic. Uh. And now I made the blooper reel. Fantastic. GUEST HOST: Should we redo the ending? How should we do the ending? 

DAVID J. MALAN: Photos of Jason Hirschhorn dressed as a pumpkin. JASON HIRSCHHORN: Oh boy. I don't know if I want people to see that. DAVID J. MALAN: No, now it's photos of Jason Hirschhorn dressed as a boy. GUEST: And if you're interested, I can actually show you how it's-- it's going-- DAVID J. MALAN: Yeah, absolutely. 

GUEST: He's a little off balance this morning. He hasn't had his coffee yet.

DAVID J. MALAN: And-- and I'm David Malan. 

RAMON GALVAN: And today I'm hosting today's episode. DAVID J. MALAN: But with me. RAMON GALVAN: Ah, OK. [BLEEP] OK. [BLEEP] 

CAMERAMAN: Don't say [BLEEP] on the air. 

RAMON GALVAN: OK. [BLEEP] He'll be the Robin to my Batman, the Andrew Richter to my Conan, the Cheech to my Chong today, which is definitely a serious thing that we're doing today. This is not a joke. 

Dropbox has made quite a fuss lately, but I know nothing about this. 

What is this about? 

That was all above me. 

And this is something I don't know of. 

We also took a tour of third glass-- 3rd D-- DAVID J. MALAN: [BLEEP] right there. It allows you to swipe credit cards on, like, your iPhone in order to process payments. RAMON GALVAN: I have a flip phone. Let's play the clip.

Although I love some Zmyla, I would much rather not spend-- DAVID J. MALAN: Spend half as much time with her. RAMON GALVAN: Exactly. 

DAVID J. MALAN: Come on out, Zmyla. 

This was CS50, and this was terrifying. RAMON GALVAN: This is terrifying. Made a nice little fizzeril to kind of encapsulate the debauchery that took place.

RAMON GALVAN: I love you. Unlike David, who circles you. 

[LAUGHTER] 

DAVID J. MALAN: Where are my slide-- Oh.
