Mannequins have a right to genitalia, Brian. Your giggling was seriously sexlessist and anti-inclusive. You're lucky it didn't happen today or you'd be rightly canceled.
Seriously, that is a funny story of a world long gone. Even more seriously I know it was not an inclusive world, but as little boys we didn't know that. I fully believe it is nice when kids don't have to grow up constantly confronted with the evils of the world.
