I had a completely wacko idea: It's the fourth of July and Phin is planning on a massive fire-work display and all that but, for reasons unknown to him, Ferb's just avoiding him. After Phin studies his history a little more he finds out exactly why we celebrate independence day, and why it offends Ferb so.
