Leslie Knope has only one man on her "Celebrity Sex List" and that man is Vice President Joe Biden. So Ben used his Washington connections to give her the best possible engagement gift on "Parks & Recreation." He walked her into a room with the vice president.

Perhaps Ben didn't anticipate just how strongly she would react, as Leslie went from shaking his hand to stroking his face. She was adorably enraptured to be in the presence of this man.

"You're very handsome," she said at one point, getting closer and closer to him until Ben practically had to pull him off.

Amy Poehler said Joe Biden was a great sport, and proved rather adept at improvisation. "The Vice President maintained his composure while I harassed him and invaded his personal space," she told the Huffington Post.

After John McCain earlier this season, the series is on a roll. Now it's about time Leslie comes face to face with Hillary Clinton, isn't it? Sure, they've met back when Poehler used to portray her on "Saturday Night Live," but that's not the same at all!

"Parks & Recreation" airs on Thursdays at 9:30 p.m. ET on NBC.

TV Replay scours the vast television landscape to find the most interesting, amusing, and, on a good day, amazing moments, and delivers them right to your browser.
