mustardog is right, this song can be beautiful and humorous at the same time. What's more, it probably WAS intended to be both at the time of its writing, as a way of softening the blow of the touchiness of the message. people who think this is some achingly beautiful, straightfaced ode to nonbinary gender are applying their own thoughts and expectations to people of 1984.
People with no sense of humor always fail to see the humor. The funny thing is in the mid-80s when they wrote this, no one got this song, so it was only considered humorous. In a few more decades the rest of the world will finally catch up to Westerberg's thinking.
Surprised people find this funny, it's disarmingly beautiful to me and pretty hopeful. The chorus is one of the sweetest moments in recorded music, or at least it is to me. I remember saying in a high school English class that gender, as in roles and expectations, is a social construct and in 1000 years won't exist, so we should quit worrying about it already. I said that with confidence and Westerberg's lyrics in mind, and the class' reaction still amuses me. Soundtrack to my teenage sexual confusion and one of the greatest songs I ever did hear
