In college, one of the dorms (Riley Hall) had these really long-legged, fast-moving brownish centipedes that we all called "Riley bugs". They had a tendency to creep people out--one time this girl on my floor suddenly let out this blood-curdling scream and when everyone else on the floor ran to investigate it turned out that she had just seen a rather large specimen scurry past her feet. Sorry I don't have a picture, but if you google "house centipede", which is what these bugs really were, you'll find plenty. Apparently they're actually beneficial--they eat other bugs like cockroach larvae and other pests. Even so, it's pretty darn hard to get past the ick factor!!!
