Woah there, this is surely an unreasonable of hate to have towards potatoes and mayo or whatever the hell is in potato salad. I respect your hatred, I will hold up a sign with your name on it and draw my vision of your potato salad hatred.
If you can make it to Colchester, Essex, and give me £40, I will do one better than make some crappy t-shirt with a funny coleslaw picture on it. For £40 I will smear homemade coleslaw on your body. I'll even take pictures with your phone so you can put it on the instagram with filters, and a whole comment full of hastags #Slawlife
