I can't tell if you're joking or not...if so, yes, you're very funny, he takes it in the butt and therefore is a rocket man.
But truth be told, Elton doesn't write the lyrics. He writes the music. Bernie Taupin writes the lyrics, then gives them to Elton, who adds the music to them. It's a strange process I'll never understand, but it works amazingly for them.
Bernie has said that "Rocket Man" is about a cocaine user, but I see it more as a tragic description of what it's like to live the life of a rock star, on the road all year, isolated from family and friends. I think that's the magic of really good lyrics, when they can be interpreted in so many varied ways.
You are correct, though - Elton's greatest hits are pop perfection!
