"Parks and Recreation": Leslie and Ben relive their high school glory days in Model UN, while Chris forms a committee to figure out his own relationship issues with Jerry's daughter (Jerry is on the committee, most definitely a conflict of interest). As Denmark, Leslie shows off her negotiating skills with Peru, a.k.a. Ben, but the unresolved feelings between them boil over quickly resulting in a world war. Ben, being the cool, calm and collected guy that he is, tries to get Leslie to wave the whie flag (no those are not dirty underwear, April), but Leslie boldly proclaims, "The only thing I will be waving is your decapitated head on a stick in front of your weaping mother." Wow, someone call the Security Council on that one. Of course, everything is resolved and once again Ben and Leslie decide to be just friends. Let's see how that goes yet again. But mostly importantly, TOM IS BACK IN CITY HALL. "Tick tock, it's Tommy time!"
