Old school calculator nerd joke.
Remember the good old days when you were still using that trusty big buttoned calculator at school? Now you can celebrate the memory by proudly wearing the 80085 Geek Girl Necklace. It's simple and direct to the point just like the old favorite device. At first glance people are going to judge you for being so bold and shameless. But don't panic, stay calm and use logic (just like in math class). Simply state the fact, that they are only numbers for a nice clean smarty-pants get away!
