De är ganska medvetna om det.
Den fjärde väggen bryts många gånger i Phineas och Ferb.
Här är en lista med scener och episoder och citat när de gjorde det.
Här är några av de bästa som verkligen visar det:
I "Agent Doof"
when everyone gets turned into babies except Candace, Candace says it had "better wear off by the next episode."
I "Wizard of Odd"
Phineas actually lifts the screen like a curtain and talks to the audience from behind it.
I "Phineas och Ferb Save Summer"
in reaction to an outburst from Phineas, Buford says "This must be a special episode, he's yelling at his sister again."
I "En riktig pojke"
when comparing the situation with Vanessa to a cheesy sitcom, both Perry and Doof stare directly into the camera.
I sommar hör till dig
Linda: It sure would be helpful if they could just make the days a little longer.
[A "ding" noise signaling an idea is heard as the bottom half of the screen is covered with an "advertisement" reading "You're Watching Television!"]
Phineas: Hey! Do you mind? We've kinda got a visual gag going on here!
[Advertisement disappears, revealing the "ding" was actually from Ferb with a triangle.]
Phineas: Thank you!
I "Den musikaliska episoden"
The kids who take the poster from the wall (just like in the pilot) are stopped by Buford.
Buford: If any one's gonna ride this roller coaster, it's gonna be me. Not one of you lousy extras.
