Aren't you a little old to be watching Phineas and Ferb? Yes, yes I am.
Seriously though, while this is a kids show, it does have a lot of subtle stuff intended for older viewers, and as one of those viewrs I wanted to create a drinking game for it. Just don't show any young kids this one.
Phinnes says “Ferb, I know what we are gonna do today!”
Someone mentions the Tri-State area
Perry unesscierly destroys some of Doctor Doofenshmirtz’s property
and chastises him for it
Major Monagram has a minor screw up and apologizes to Perry (drink two)
Candice tries to bust the boys
“Hey, where’s Perry?”
“Doofenshmirtz Evil Inc.” jingle (drink two)
Candice crushes on Jeremy
A song (drink three)
Vanessa shows up (drink two)
Someone thinks Doofenshmirtz is a pharmacist (finish your drink)
Isabella says “Whatcha dooooin’?”
That noise Perry the Platapus makes
Linda reference her musical days and/or preforms
Someone asks “Aren’t you a little young for…”
…to which Phinnes responds, “Yes, yes I am.”
Other O.W.C.A. agents are shown
Ferb actually says something (drink three)
Someone says a different character’s catch phrase (drink four)
Doofenshmirtz shouts “Curse you Perry the Platapus!”
And finally drink for “Oh, there you are Perry”
