On 'Late Night With Jimmy Fallon' (weeknights, 12:37AM ET on NBC), comedienne Amy Poehler expressed her "love" for Rashida Jones, her 'Parks and Recreation' co-star. But then, Amy's enthusiasm turned out to be kind of ... infectious. And not in a good way. More like infectious in a creepy way.

After Poehler declared her love for Rashida, host Jimmy Fallon became overtaken by the spirit of romance. Who did he express his undying passion for? Questlove, the 39-year-old male drummer for The Roots, Jimmy's house band. "I love ... Questlove," he said, in a slightly too intense tone of voice.

Amy started to sing a romantic ballad about Ms. Jones, then Rashida showed up to make it into a duet. Fallon then took over and began serenading Mr. Questlove. Unfortunately, the song that they all chose to belt out was the fairly terrible "Tonight, I Celebrate My Love." Which contains lyrics like this:

Tonight, our spirits will be climbing
To a sky filled up with diamonds.
When I make love to you, tonight.

So while it was nice to hear Jimmy express his sincere desire to "make love to" Questlove, the drummer seemed a little freaked out. The quizzical yet horrified expression on the guy's face kind of said it all.
