Blonde joke

A blonde is trying to hammer down a pin into a wall, she has the flat end to the wall and is hammering the pointy end. She gets really pissed as it clearly isn't working. Her friend comes in and asks whats wrong. "Well, this pin just work! It's not piercing this wall!" she says.
Her friend looks at her and says " You idiot, You got the wrong pin! That pin is clearly for the wall on the oppsite side!
