In animation class, we had to make an E-Card. My teacher said I could make up a holiday or event if I wanted, so I did.
Why July 13th? When I was trying to come up with a day, I thought "It should either be Halloween or the day Sonic R was released", come to find out, Sonic R was released on Halloween (how 'bout that?), so I went to the day it was released for the PC in Europe (just because).
No, you do not have to take this seriously. Yes, it looks like crap.
For all others, be sure to celebrate this every year from now on.
