Every comicâs mission is to amuse and, if theyâre really good, to make us think. As a stand-up, Oswaltâs long done both on TV (âKing of Queens,â âJustifiedâ) and film (âRatatouille,â âYoung Adultâ). But right after the horrific blasts at the Boston Marathon, Oswalt did much more in an essay that lighted up social media, reminding us of humanityâs goodness just when we needed it most. Seriously Âż thanks, Patton. (Gary Friedman / Los Angeles Times)
