A young woman was sunbathing on the beach and was just about to drop off to sleep, when she felt an insect running along her jawbone and then down her neck. She brushed it away, and thought nothing more of it.
After about a week, she noticed what she thought was a pimple growing and growing. The skin was inflamed and it looked like a blister. Then, one day, she was blow-drying her hair and hit the inflamed spot with her hair dryer. The blistered skin broke open and hundreds of tiny white baby spiders and pus came pouring out of the wound!
It seems that while she was sunbathing, her pores had enlarged enough that a mama spider could deposit her egg sac in one. They incubated under her skin until she smacked herself in the jaw with the hair dryer.
