Back for the Future2011

Store Clerk:
[sits down with a yellow shoebox] Glad you're sitting down, sir. Because this right here is the finest footwear available on the market today. Let me introduce you to... [opens the box] the future!

Customer:
[takes one of the shoes out] Wow. Man, this is heavy.

Store Clerk:
Not heavy at all. It's actually quite light. Speaking of lights... [presses the top of the shoe, its logo and bottom light up] Four hours on a single charge.

Customer:
[absent minded at first] That ain't my density. Uh... I mean, my destiny.

Store Clerk:
Whatever you want!
