THERE WAS NOTHING BUT METHANE ON PLANET D

There was nothing but methane on old planet "D",

Then, I lit up my cigar and the planet went "B",
Oh what a day,
It blew me away,
Now, I'm flying at light speed by old planet "Z".

THE CURRENCY OF OUTER SPACE

I hitched a ride to Mars,

It cost me 6 cigars,

I couldn't take my pets,

That cost cigarettes,

And, I'm saving those smokes for the stars.
