I just ran across this and I have to post my own similar story .. .
It was, I think, in 1992. I was on my bed reading late at night, when I noticed that there were lots of things crawling on my arm, and on my lamp and on my bed. Looking more closely I realized that there were
hundreds of tiny, tiny white spiders. I squashed the ones on my arms and followed the trail of webs that they were spinning. They were crawling all over the lampshade and I traced the webs to my AC unit which was also covered in spiders and webs. From there I followed the webs down to a space underneath my dresser drawers where I found the mother (as in parental unit) of the spiders. And this one was very clearly a black widow spider. There was an egg case which still had some of the babies coming out.
I which point I freaked. My apartment was swarming with lots of dangerous, poisonous spiders that had been crawling on me and my bed for who-knows-how-long before I noticed.
Fortunately, none of them seemed to have bitten me and I spent the next three hours squashing every one I could find between my fingers. It was the only way I could find that didn't require DC 20 dex checks.
When that was done I turned my attention to the mother spider. Where it was I couldn't squash it without being totally sure it wouldn't somehow bite me. After about an hour, I managed to use a can of chain lubricant to force it out of its hole and trapped it inside of a jar. I seeled the jar up and put it in the freezer.
For about a week after that I showed my trophy to my friends and bragged about all of the xp I must have earned.
Interesting fact: Baby black widows are white.
Now I am freaking out again and pulling my legs up onto the chair lest there be something underneath my computer desk.
