Tele-bone
Explanation
Explain Bear
Okay, so basically, Papyrus wants Sans to call Undyne about a human they found. Sans says he'll use the "Tele-bone," which is a pun on "telephone" using the word "bone" because Sans is a skeleton, bonehead. Papyrus is annoyed by the dumb joke. Sans is known for making bad puns. You probably didn't get that because you also make bad jokes.
