Boy, that rabbit hole just gets deeper and deeper these days.
To those of us that watched the cartoons when they were new the warning seems ridiculous but then again we (a) have a sense of humor, (b) can readily discriminate between fiction and non-fiction, (c) know that cartoons are in an alternate universe with a separate set of rules, (d) were taught to disregard the perpetually indignant and (e) played with mercury when we were kids.
If I had kids I’d buy them a full set just on general principles.
I hope whoever owns the T&J franchise makes a bundle on the publicity.
