While working the Jumble and looking at "onpti", Peg asks if "nipto" is a word and then decides the answer is "pinto". However, the correct word could be "point". She wouldn't know which it is until she tried to solve the cartoon's caption and whether she needed an I or an O (whatever the second letter of the correct word is).
[Continuity Goof]: Missy rips Sheldon's autographed picture of Professor Proton in this episode. Sheldon tapes it back together, but the rip can still be clearly seen. In season six, episode twenty-two of 'The Big Bang Theory', Sheldon shows the same picture to Professor Proton but the rip is not visible. Since 'Young Sheldon' takes place while Sheldon is a child and 'The Big Bang Theory' takes place when Sheldon is an adult, the rip should have been visible in the episode of 'The Big Bang Theory'. [Correction]: The "Continuity Goof" does not occur in this episode of 'Young Sheldon', but in s6e22 of 'The Big Bang Theory'.
