Summer is done
And we've had our fun
But this isn't the end of our story
So for nostalgia's sake
Let's just take a break
Sit back and take inventory
We've done so many wondrous things
And there's still so much to do
But I make the most of every day
Whenever I'm with you
Because...
It's not about the summer sun
Or even all the things we've don
It's not about the change in the weather
It's just about the time we spend
With our family and with our friends
It's just about the time spent together
It's just about the time
Not the weather
It's just about the time
Spent together

Phineas: It started real simple with a cool rollercoaster
An awesome beach party, then we raced stock cars
We were one-hit wonders with a big hit song
And in a special two-parter, we sent Candace to Mars
Phineas and Danny Jacob: We built tree house robots, hunted bigfoot and a mummy
Got the band back together and our parents, too
Candace: When my brothers got busted, it was only a dream
Phineas: But who had that dream, was it Perry or you?
Candace: Actually, I think my dream was inside of Perry's dream
Buford: My mind is blown
Phineas and the cast: There's been 104 days of summer vacation
We've had a lot of fun, and sung a lot of songs
So now it's time for a big celebration
'Cause it's been a great summer
And we thank you for comin' along
Thank you for comin' along!
Thank you for comin' along!
Doofenshmirtz: I'm six foot two, and I fight a little platypus!
Ya think I'd be victorious just every now and then
I've had a whole lot of schemes and a lot of inators
But I failed
Over and over
And over and over again
Aw, but it was fun, though
Phineas: We spent a day fighting pharmaceutical zombies
Would've solved cold-fusion but did fashion instead
We met Klimpaloon and Meap and the Lake Nose Monster
Phineas, Candace, and Ferb: But we're still baffled by the Giant Floating Baby Head
Phineas and Isabella: We played Hockey Z-9 and Football X-7
We went 'round the world and to the very edge of space
Phineas and Baljeet: We met our doppelgängers in the second dimension
Phineas: Isabella kissed me but I got my mind erased..
Wait, what？
Phineas: You just wait 10 years
Everybody: There's been a hundred and four days of summer vacation
We've had a lot of fun, and sung a lot of songs
So we think it's time for a big celebration
And it's been a great summer
So we thank you for comin' along
Everybody: Thank you for comin' along
Anyone want some pie?
Yes. Yes we do
Aaron: It's just about the time
We spent together
It's just about the time
We spent together
With you
