Why Pigs?

My sister is obsessed with pigs, so obsessed that she painted a pig onto her forhead, I don't what you think but I think it's rediclous. My sister got this giant pig floaty thing for Christmas. We tried it out at our uncles indoor pool. The color came off of it so now his pool is pink. My dad said he would pay for the new water and every thing. But my uncle insisted that he couldn't. After all he is a pretty wealthy guy.
