Guys you disappoint me. Mr. Yuck was a warning sticker for small children to keep them out of possible household poisons (invented mainly because as piratey things grew in popularity kids associated skulls and crossbones with cool toys rather than danger and death). What I really remember (well remember best at least, but I was pretty little at the time) was my best friend (who had older siblings) had Mr Yuk stickers before we did so I was excited when we got them and could help put them on all the bad stuff. Besides what little kid doesn't like putting stickers on stuff (right you guys because you just want to ruin all my examples
)
