Here are the lyrics.. I don't know who it's by. I found it on some tape my dad has.

Intergalactic Laxative

I was impressed like everyone when man began to fly
Out of earthly regions, to planets in the sky
With total meter coverage, we watched our heroes land
As ceremoniously they disturbed the cosmic sand
In awe with admiration we listened to their talk
What a pride-felt day, such joy to be upon the moon to walk
My romantic vision shattered when it was explained to me
Spacemen wear old diapers in which they shit and pee

Oh, the intergalactic laxative will get you from here to there
Relieve you and believe me, without a worry or care
If shitting is your problem when you're out there in the stars
Oh, the intergalactic laxative will get you from here to Mars

They dump partake like you and I, of beefy burger mush
Their food is specially prepared to dissolve into slush
Absorbed by multi-fibers in the super diaper suit
Otherwise the mush would trickle down inside the boot

Oh, the intergalactic laxative will get you from here to there
Relieve you and believe me, without a worry or care
If shitting is your problem when you're out there in the stars
Oh, the intergalactic laxative will get you from here to Mars

You well now ask what becomes of liquid they consume
A pipe is lead from penishead to a unit in the room
The water is recirculated, filtered for reuse
In case of antigravity and pee gets on the loose

Oh, the intergalactic laxative will get you from here to there
Relieve you and believe me, without a worry or care
If shitting is your problem when you're out there in the stars
Oh, the intergalactic laxative will get you from here to Mars

Where ever man has conquered
On the quest for frontiers near
I�m glad he�s always had to do
The #1 and 2
It makes it all so ordinary
Just like you and me
To know the greatest heroes
They had to shit and pee

Oh, the intergalactic laxative will get you from here to there
For cosmic constipation, there's none that can compare
If shitting is your problem when you're out there in the stars
Oh, the intergalactic laxative, the intergalactic laxative
Oh, the intergalactic laxative will get you from here to Mars
