It's very simplistic, but my failsafe remedy, at least temporarily (depending on the size of the zombie) is a good old fashioned icecream cone. I'm an optomist by nature, and usually try to make the best of things or least remember the old saying "This too shall pass", but an icecream cone always puts me in better spirits. I love icecream to begin with but there's something about eating it on the cone that never fails to raise my spirits, especially with one of those decadent waffle cones drizzled with chocolate. Maybe it's giving into my sweet tooth. Maybe it brings back feels of the innocence of childhood. Maybe it's the usually taboo act of sticking my tounge out in public. I don't know, but it works for me! :p
