Incorrect About the Sex Pillow

So It turns out that the so called "sex pillow advertisement" was not what I thought. Apparently parking is so crazy in Korea that you have to illegally park and block cars in if you ever want to get spot, so they put their cell phone numbers on the dashboard so the blocked person can phone you and get you to move. Here is what i find funny, why would you spend money on a embroidered pillow when a nice white cardboard with your number on it would suffice. I guess its the same reason why women spend thousands of dollars on a purse (extravagance)
