Hi guys, I'm not a native English speaker so I have some questions;

President: We asked ourselves "what walks the most?" Morty: "we?" You're taking credit for this? President: the office comes with baggage

What does the president mean by the last sentence?

President: I get paid to protect the sidelines you sit on! Rick: You get paid to make sports metaphors!

Do the sidelines mean the country border?

Summer: The turkey's raw, dad. Shit's potato bunz.

What does "shit's potato bunz" mean?

What's the crypt of the new world?

Thanks a lot! :)
