In a freak lab accident with his buddy Frank N. Stein, he had a combonation of peroxide, choloride, vinegar, iodine, sulfur, and chlorine in a cup. He put it on a hot plate. It started to boil. All of a sudden while Frank had his back turned, Jebis was caught right in the middle of the explosion. His eyebrows and eyelashes zapped and fell right out.
JEBIS: OH MY GODDDD FRAAAAAAAANK!!!!!
FRANK: Jebis! What happened?!
JEBIS: I lost my facial hair!!!!!!!!!!!!!!!!!!!!!
FRANK: OH MY GODDDD!!!!! How will anyone know you are a MAN?!
JEBIS: I don't know Frank.
