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 to be a great day! Crossing the tundra or building a roller coaster Or 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 to 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 suppliers Yogurt, gumballs and desire And a pocketful 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 (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)
