A drab soul named Johanna Parry has just become convinced that, at long last, someone in the world loves her. The someone lives elsewhere, so physical affection will have to wait, but Johanna has been waiting too long already. So she stares at the bathroom mirror and then forcefully tries out some kissing on her own reflection. With tongue. This action would be normal for a 14-year-old, but for a grown woman it takes on different shades of sad, funny, and mortifying.
The moment might defeat an ordinary actress, but Kristen Wiig is not ordinary. And she really goes for it.
