I heard it a long while ago.

[Rainshadow]

A coffin!

 Yay!!!  You win!  I got a really good one, do you guys want to hear it?

[Redwaller]

yes!

[Rainshadow]

  There are three cubicles right next to each other.  One cubicle is owned by a red-head, one a brunette, and one a blonde.  There is nothing on their desks except a computer.  All three of them have gone out to lunch.  How can you tell which cubicle the blonde works at?

[Popcornman]

the blonde was googling how to use a computer

[Rainshadow]

  No she was out at lunch with her coworkers.  There's nothing on the desks except a computer.  How can you tell which one is the blonde's?

[psybox]

fingerprinting.

[Rainshadow]

  Nope.  Do you guys want a hint?

[Griffen]

the blondes computer is off.

[Rainshadow]

  Nope, but you guys are guessing in the right direction with the computers.

[Skyblade]

I never heard this one....does the blonde's computer say something the other's don't?

[Rainshadow]

  Nope.  Just letting you guys know, there's nothing running on the computer.  It has something to do with the screen.

[Skyblade]

Can you PM me the answer?

[Dannflower Reguba]

Is the Blonds all dented, or smeared with something, or still on?

[Rainshadow]

  Close with something being on it!  Getting really close!  Do you want a hint?  This isn't really an obvious answer.  You'd have to be older to get it.
