Welcome to Class

September arrives at Danville and Phineas, Ferb and their friends must return to class, the change is that a new excentric and obsessive teacher is at class, and, he is the biggest fan of "Phineas and Ferb"; the whole class finds him a bit weird but they will end likin' him and helping him to get a date with Vanessa Doofenshmirtz, meanwhile, Dr. Doofenshmirtz is a bit worried about the new kid that is interested on his daughter.
