Brain surgery makes me think of Career Shadowing. (I career shadowed a veterinary surgeon, and watched dogs and cats being operated on all day. My mom was the one who called the office for me, and she decided I should be in the O.R. =P)
ballparks make me think about fruit and yogurt smoothies from dunkin' donuts (I've wanred people I'm random..actually theres a whole story behind that XD)
