Flashing Back to Fashion Forward

is the first song of the Phineas & Ferb special "The Klimpaloon Ultimatum". It is sung by Mittington Random and is about his plan to use the Klimpaloon for his new line of swimsuits.

Lyrics
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!
