I wrote the following when I was in about sixth grade. This was my first filk song and I didn't even know what a filk song was. But Kids write them all the time. Twinkle Twinkle Little Star Up above the Planet Mars. Two light years from the Moon complex, Twenty from Planet X. And what's the orbit, when and where?
Calculations made all day, On how much we'd have to pay, To send two Astronauts up there, And what's the orbit, when and where? Then the day that blast off starts. Last check around for missing parts.
The countdown’s slowly counting down. The two take their last look around. Then they discover as they stand, That they've forgot a bathroom plan!
