Episode Title:Nerds of a Feather.Episode Description:Phineas and Ferb head to the Tri-State area's annual sci-fi/fantasy convention to meet their hero, special effects guru Clive Addison. Their plan gets sidetracked when they're swept into a duel between Buford and Baljeet, and their respective clubs of fantasy fans and sci-fi geeks. Meanwhile, Candace tries to keep secret that she's a fan of Ducky Mo-Mo (which is a children's show with an adult fan base, somewhat like the bronies of the My Little Pony fandom), another convention staple. Across the convention hall, Dr. Doofenshmirtz has taken television executive Jeff McGarland hostage so he can pitch him a show he's developed, Doof 'n' Puss.
