Headscratchers / The Andy Griffith Show

• In the episode "Mr. McBeevee" Opie tells Andy about his friend whom Andy believes he made up. When Opie shows him the quarter that Mr. McBeevee gave him, Andy apparently comes to the conclusion that Opie stole the quarter. But even if he still believed Mr. McBeevee was imaginary, why would he fall to that conclusion? Opie could just have found it lying on the ground and picked it up.
