This is a great t-shirt choice for those who grew up to be guys their mothers told not to mess with. Parental advisory shirts were extremely popular in 90s. And they are still pretty cool, especially for those who like Woody Harrelson. He wore one in White Men Can’t Jump movie. Also, one of George Carlin’s stand up albums is called “Parental Advisory Explicit Lyrics”, so it’s a good choice for those who like him, too.
