In an effort not to squeal like a little girl while jumping and running from the car I:
1)took his picture and sent it to my blog (of course!)
2) found a chuck-e-cheese token cup in the car and trapped him under it
3)realized that chuck-e-cheese token cups have holes in the bottom so you can't use them for soda or apparently for trapping humunguous spiders
4) stuck receipt under the cup and flung the door open throwing chuck-e-cheese, receipt, and spider out into the lot
5) apologized to the woman next to me for banging her car with my door. no worries though as she was laughing her ass off at me.
