Schadenfreude: Pleasure derived from the misfortunes of others.
Example: When I [Lloyd Grove of the NY Daily News] suggested to Franken that I didn’t believe him [regarding that he had “no comment” about O’Reilly’s recent legal woes] and that he must be having his own little schadenfreude festival he conceded: “Well, if this is true, there’ll be enough schadenfreude to fuel … uh, no comment, no comment!”
