Here's a hilarious image from SLS Scheibe of the SLS Lines called Math Geek. You all know I was an electrical engineer in college, so I have taken so many math classes that I totally had to get this image. TOO funny. I created this hilarious sentiment, perhaps only math geeks get it, "My girlfriend is like the square root of -1...she's imaginary."
Then I had to decorate the card with a bunch of -1 button themes. Hope my brother likes it, he was a math major in college. Check out SLS Lines other fun images at her Etsy store, there's everything from quirky images like this to beautiful fairies.
