Anything with more than 6 legs gives me the heebyjeebies. (I used to scream every time I saw a spider until we moved to the country and I was afraid of mucking up my vocal cords.) When someone teases me with spiders (they usually only do that ONCE) I come out swinging. The FIGHT OR FLIGHT instinct kicks in wildly.
Driving over high bridges gives me anxiety attacks as does some situations with crowds. Not sure I would categorize those as phobias though.
