Phineas has donned the persona “Elvis Parsley”

Phineas: … and all my fans have to pay me bribes …
Ezra: If you try to make your fans pay you then you won’t have any fans.
Phineas: Yes I will! I’ll sue them!
Ezra: Why would they be your fans if you sue them?
Phineas: Because they’ll think that if they’re my fans, I won’t sue them again. But then I will sue them again!
