Lena Dunham may have stopped by "Late Night with Jimmy Fallon" Wednesday night to talk about her show "Girls," but before the interview started she wanted to clear the air about something. Namely, the huge crush she had on Jimmy Fallon when she was in high school.

And this wasn't your run-of-the-mill, watch "SNL" every week kind of crush. Over the years Dunham collected a signed napkin and even wrote a play about the two of them switching bodies and falling in love.

Somehow, though, the entire thing comes off as entirely endearing and not even remotely homicidal -- a real feat as far as teen obsessions go.

Watch the full clip above and check out part two of her interview here.
