Question

Kellen was playing some more World of Tanks....

He played so much WOT that he worked up an appetite.

Kellen ripped a PDF in half. He then treated these two halves as bread and placed a different PDF on the inside (yummy PDF meat!). That sounds like one good PDF sandwich. PDF on the outside and inside! YUM!

Hint

You are going to have to find a way to remove the PDF from inside the other PDF file.
