The Perfect Pun

i can't seem to understand what the puns are saying. 

IT'S FUNNY BECAUSE NAZI SOUNDS LIKE NOT SEE

[jkid101094]

During World War II, Norwegians were prohibited from wearing any buttons with the likeness or initials of their king on them. In protest they started wearing paperclips, because paperclips were a Norwegian invention whose original function was to bind together. This was a protest against the Nazi occupation and wearing a paperclip could have gotten you arrested.
