Boyfriend From 27,000 B.C.

Episode Summary
The episode starts out with Phineas and Ferb watching an interesting prgram on their television called "Cavemen" causing them to eventually decide to find a caveman in the Danville Glacier while Candace is upstairs trying to find something to wear for Stacy's costume party. Candace gets a call from Jeremy and he says he is going as a caveman which causes Candace to go as a cavewoman. As Phineas and Ferb gather supplies for cavman hunting, their parents leave for the Historically Relevant Botanical Gardens, while Perry heads for his lair. Stacy asks Candace to make a sandwich platter and goes off to do that while Phineas and Ferb head to the Danville Glacier.

Perry uses a card to pick the lock of Dr. Doofenshmirtz's door and ends up getting stuck in one of his traps while Dr. Doofenshmirtz rants about his scheme to rid the Tri-State Area of one of his biggest pet peeves, people who dress as sandwiches to advertise restaurants.

Phineas and Ferb are shown bringing home their newly found caveman, Conk.

Dr. Doofenshmirtz flies off in his new invention and Perry the Platypus breaks free and flies off after him.

Conk's hunger forces Phineas and Ferb to go wrangle up sone snacks for him but while they are gone he notices Candace with her paltter of sandwiches and euns off after her. Candaces notices him and thinks he is Jeremy and so she introduces him as that at the party so everyone believes that. Candace then gets a call from Jeremy and realizes that this caveman is in fact not Jeremy. She calls her parents about it while being carried by Conk and her parents of course don't believe her.

Dr. Doofenshmirtz is out using his invention to remove the sandwich costumes but Perry comes along to stop him, while Phineas and Ferb find Conk and take him away from the party. Perry knocks the half eaten sandwich suit out of the mouth of Dr. Doofenshmirtz's removinator, as well as Dr. Doofenshmirtz as Phineas and Ferb feed Conk sandwiches. He then crashes te removinator into Danville Glacier and parachutes away. Dr. Doofenshmirtz emerges from bushes in the sandwich suit and attracts Conk to eat him. Dr. Doofenshmirtz runs off with Conk chasing him.

The "Too Young" Line
(none)

Ferb's Line
(They say if you love something, let it go) Especially if it is a caveman.

Perry's Entrance to his Lair
Perry scuttles up a storm drain and pops out in mid-dressing of a magpie costume, then walks onto a power line scaring off some magpies, and hops into an emergency phone on the phone line pole, ending up falling from the ceiling of his lair landing into his chair.
