(CNN) An unexpected visitor hitching a ride caused a rollover car wreck in Oregon.

An itsy bitsy spider dropping down from a rearview mirror caused a woman to lose control of her car and go off the road Wednesday in Portland, deputies with the Washington County Sheriff's Office told CNN afiliate KATU

The driver wasn't seriously injured, just a minor scratch on her hand, but she'll have a heck of a story to tell her friends.
