Can I have some non-poisoned, perfect tasting, never-go-bad, bone-in, perfectly healthy buffalo chicken wings in a magical, bottomless, unbreakable bowl that only allows our arms and the wings to pass through its magical barrier, and is always filled to the brim, with no possible way to harm any part of me in any way at all, as well as some bleu cheese dressing and hot sauce with the same attributes, a neverending craving for the foods, and a bottomless pit of a stomach?
