Today is Gonna Be a Great Day

"" is the full version of the series' theme song. It is performed by the band Bowling For Soup. The song is composed in a fast, loud rock styling, but was originally written as a slow song with a light chorus, based on classic Disney songs. Many stanzas in the song are at least closely resembling actual adventures and inventions Phineas and Ferb take part in throughout the series, while others are merely interesting things the boys could possibly do. The song first appeared in its entirety in the episode "Phineas and Ferb's Quantum Boogaloo," and then was released as part of the official series soundtrack.

There's a hundred and four days of summer vacation,

'Til school comes along just to end it,

So the annual problem for our generation,

Is finding a good way to spend it

Like maybe…

Building a rocket, or fighting a mummy,

Or climbing up the Eiffel tower,

Discovering something that doesn't exist,

Or giving a monkey a shower

Surfing tidal waves, creating nanobots,

Or locating Frankenstein's brain,

Finding a Dodo bird, painting a continent,

Or driving our sister insane!

This could possibly be the best day ever!

(This could possibly be the best day ever,)

And the forecast says that tomorrow will likely be a million and six times better.

So make every minute count, jump up, jump in, and seize the day,

And let's make sure that in every single possible way,

Today is gonna be a great day!

Crossing the tundra or building a roller coaster.

Skiing down a mountain of beans,

Devising a system for remembering everything,

Or synchronizing submarines.

Racing chariots, taming tiger sharks, constructing a portal to Mars,

Building a time machine, stretching a rubber tree, or wailing away on guitars.

(Oh, man.)

This could possibly be the best day ever!

(This could possibly be the best day ever)

And the forecast says that tomorrow will likely be a million and six times better.

So make every minute count, jump up, jump in and seize the day,

And let's make sure that in every single possible way,

Today is gonna be a great day!

Hey! Hey! Hey! Hey! Hey! Hey! Hey! Hey!

Let's put our heads together and design a master plan.

We may miss dinner, but I know mom will understand…

We've got our mission and some pliers, yogurt, gumballs, and desire.

And a pocket full of rubber bands, the manual on handstands,

A unicycle, compass, and a camera that won't focus,

And a canteen full of soda. Grab a beach towel, here we go!

(This is Ferb-tastic)

This could possibly be the best day ever,

(This could possibly be the best day ever)

And the forecast says that tomorrow will likely be a million and six times better,

So make every minute count, jump up, jump in and seize the day,

And let's make sure that in every single possible way.

(Seriously, this is gonna be great.)

This could possibly be the best day ever.

(Today is gonna be a great day!)

This could possibly be the best day ever.

Today is gonna be a great day!

Production background

 * The creators (Dan Povenmire and Jeff "Swampy" Marsh) originally wrote a slower number as the theme song, more like a "classic Disney song", but the network felt changes were needed to appeal to modern children and commissioned a rock/alternative version which made the final cut. (Original Pitch)
 * The song first appeared on television during the episode "Phineas and Ferb's Quantum Boogaloo." The following day, it was released as part of the official series soundtrack.
 * In the other languages' versions of the episode 'Phineas and Ferb's Quantum Boogaloo', the song isn't translated, probably due to copyrights issues with Bowling for Soup.

The episode "Phineas and Ferb's Quantum Boogaloo" shows more literal examples of the Big Ideas described in the song:


 * Skiing down a mountain of beans
 * Devising a system for remembering everything
 * Taming tiger sharks

One final Big Idea has not yet been shown in any fashion:
 * Finding a dodo bird - Not attempted yet, but since in "Phineas and Ferb's Quantum Boogaloo" they expressly stated that they will never again go in the future, they just might go in the past when they do attempt it. Note: Although they never actually found one, Agent P turned into one during his fight with Doofenshmirtz and the De-evolutionator.
