There's a hundred and four days of summer vacation,
'Til [bad word] 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 rollercoaster,
Skiing down a mountain of beans,
Devising a system for remembering everything,
Or synchronizing submarines,
Racing chariots, taming tiger sharks, [bad word] a portal to Mars,
Building a time machine, stretching [bad word] 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 [bad word] bands, the manual on handstands,
[bad word]  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!
