I swear I remember some rumor from back in the day that Carmex was somehow addictive: You'd put in on your lips to keep them from drying up, but Carmex had fiber glass in it, which would make tiny cuts on your lips, which made them dry and crack even more, so you then you had to use more Carmex, rinse and repeat.
Thanks for unlocking that memory for me. The 80s were a weird time.
