he is the symbol for poison. can't remember his name (Mr. something). a buddy back in high school had him tattooed on his ankle (like '90/'91). we had a sticker of him and the nuclear assault smiley face stuck on the back window in chem class.
If i remember right the mr.yuck stickers they gave out in the 80's were green and black not green and white. Lol i'd bet that i could still go back to my mom's house and find an old bottle of something out in the garage with a mr.yuck sticker on it.
