Every comic’s mission is to amuse and, if they’re really good, to make us think. As a stand-up, Oswalt’s long done both on TV (“King of Queens,” “Justified”) and film (“Ratatouille,” “Young Adult”). 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 humanity’s goodness just when we needed it most. Seriously ¿ thanks, Patton. (Gary Friedman / Los Angeles Times)
