|Secret Agent Sherman / Alexander Cartwright|
|Season 2, Episode 9|
|Peabody's Diet / Ponce De Leon||Sherman Exchange Program / Charles Dickens|
A agent spy comes to the show and shows off his gadgets to Mr. Peabody and Sherman. This gives them an idea to do a spy-themed show; Alexander Cartwright invents baseball and challenges Mr. Peabody, Sherman and their friends to a friendly game. However, Cartwright keeps changing the rules, which prevents a fair game and anyone from having fun.
- Wheh Sherman says, “The name is Man. Sherman.” is easily a reference to James Bond.
