Flashing Back to Fashion Forward is the first song of the Phineas and Ferb episode "The Klimpaloon Ultimatum". It is sung by Mittington Random and is about his plan to use the Klimpaloon for his new line of swimsuits.   


Mr. Random: We're flashing back to fashion forward!
Yes the old is the new new!
One size fits all with just a little stretching
Be you six-foot-four or five-foot-two!
Why rely on inspiration
When the old stuff's tried and true?
We've just revamped a tired idea
And made a new old-timey swimsuit for you!
