Irony? Or just plain evil?

Quick annoyance of the day: Pantene gives away $1 to cancer research for every bottle sold. Pantene shampoo contains carcinogens such as retinyl palmitate and oxybenzone and dmdm hydantoin (okay, so that one is a possible carcinogen, but whatever). And THIS is why I hate those stupid walks for cancer. They're almost all sponsored by companies that fucking cause cancer.
