From the script:

Chris, welcome to the lingerie department. What are we doing here? When I was young, seeing these half-naked mannequins was all I needed to get me going. What's the endgame here... Him walking around Macy's with a chub? No, we've got to reset his arousal meter. He needs to be able to use his imagination again. Any of these mannequins doing anything for you, Chris? Uh, I don't know. I guess the one without a head is pretty cool. All right, that's... that's something. And that bin of chopped-up ones over there... that could be okay. 'Specially the one that looks kind of afraid. There you go. Look at you. Sounds like someone is ready for that date. Do you gentlemen need any help? No, thank you, dear. We're just trying to get my brother to full mast.

And this from the script regarding pizza.. you have to watch the scene to get the full context.. they are looking at the camera and grinning and the pizza cooking has no part in the plot.. it's obviously put there as a reference to PG.. later on there's more about fake news, trump and the boys at DC..? The whole episode is quite revealing ..

You ready for your date? - You bet I am! (KNOCKING) Hi, Chris. (LAUGHING) Hi, Kristen. Ready to see a Marvel movie, 'cause I chose? Sure. And for sure this is a real date, and me and the popular kids aren't gonna thrill-kill you tonight. I think Chris is gonna be just fine. (HIGH-PITCHED BEEPING) Which is more than I can say for our pizza. (BOTH LAUGHING) Oh, man. Well, I hope you're happy.
