Duh, everyone knows spiders have 6 fangs, 14 1/3 eyes, and 10 legs....I mean seriously, who doesn't know that? :}No offense if I seem way off the mark, but seriously, a spider with FOUR fangs??
I think he meant its second fang broke before it could get the second bite in, which would result in three holes....right? Either way, it's not caused by a spider, I vote ants.
