@Nathan - Do you remember Madras shirts back in the 70s? The print (usually plaid) was meant to bleed the first time you washed it, and the more it bled, the better. My mom and grandma thought that was an atrocious idea, but my older brother wanted one really bad so dad bought it for him. Seems weird now, but that stupid shirt was the family's main topic for weeks.
Grant only wore that shirt a few times. I don't remember why he lost his enthusiasm for it, but I bet he'd have wanted peed-on pants if they had 'em back then. He liked novel ideas, especially if they were shocking but harmless.
