I can't recommend A Very Potter Musical, or A Very Potter Sequel--because they're just too indecent. And this scene was a lot less innocent than the stamp might look. But that the plays could turn me into a giggling, singing fangirl in the space of two YouTube-filled evenings says something for their construction. Or maybe my weak will, having been loosened by tons of great HP fanfiction. Whichever.
So, look up the songs on YouTube, look up Darren Criss and his genius, but please don't watch the plays because of me. They have some seriously foul points, playing under and in their catchy tunes and weird recurring jokes.
But yes, the reason that I'm posting this is because: 1. I'm a fan of HP fans, and 2. I love the cheesy moments in movies where a guy kisses his girl and can do anything he needs to for the following five minutes. Totally improbable and cliche, but it brings out my inner chick flick lover.
