[APPLAUSE] [VOCALIZING] 

ISA BERLINER: (SINGING) We're strolling along Mass Ave. We're sitting by Widener. We're rubbing John Harvard's foot, wishing for the best. Praying to the Ivy gods, thinking man, what are the odds that Harvard is the place I'll manifest? 

Now Ivy Day has arrived. You're nervous as ever. Crowding around a tiny screen. Heart beats as you wait. 

[APPLAUSE] 

Pick this up and click. Congratulations, you're in. Oh, this, this could be the start of something great. Now Visitas has come upon us. Let's all shop a class. Who knows what David Malan has in store? Learning scratch, JavaScript, CSS, SQL, C, and Flask. Getting free food, who could ask for more? 

Next thing you know, fall is here and it's your first P set. You can't get the Scratch cat to do its little dance. Oh, suddenly it's Sunday night. Everyone's in such a fright. Oh, this could be the start of your next chance. 

TRIO: You're freaking out. It's week 2. You've only just started it. You're actually calling out, or so you might do. You've never done this before. That's why you can't handle more. You don't see how you're going to sleep a wink. Don't stress, your TFs are there. They're ready to help you. A legion of programmers at your beck and call when all of a sudden, you look up at and the error's gone. Oh, maybe you can code well after all. 

ALL: Who knew that coding for the first time would be such a rush? Or the first time you built binary search, binary search? Or that your first day here on campus would be a straight flush, and you'd go home with CS50 [INAUDIBLE]. 

ISA BERLINER: Next thing you know, winter's here and it's the last lecture. You walk into Sanders, and lights start to shine. Wow, how the semester's flown. Your confidence has grown. And this could be the start of something, this could be the heart of something, this could be the start of something fine. So fine. So fine. So fine. 

[APPLAUSE] 

KATIE BURSTEIN: Thank you so much. We are the Radcliffe Pitches, Harvard University's oldest treble voice jazz a cappella group, founded back in 1975. And it is such an honor to be singing with all of you tonight. I hope you are all enjoying a Visitas, albeit a little bit rainy. 

But if you are interested at all in singing, the Pitches are actually having an open rehearsal later this evening in Farkas Hall 203. You can join us, and we promise not to make you sing CS50-related lyrics. Now at this time, I'd like to invite our sibling group, the Harvard Krokodiloes, on stage to join us. We hope you get a kick out of it.
