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!
As you can see
There's a whole lot of stuff to do
Before school starts this fall (Come on Perry)
So stick with us 'cause Phineas and Ferb
Are gonna do it all
So stick with us 'cause Phineas and Ferb are
Gonna do it all!
(Mom! Phineas and Ferb are making a title sequence!)
