Old Hippie-

"If you wish to pass some water
Kindly call the pullman porter
He'll leave a vessel in the vestabule
If the porter isn't near
Then try the platform in the rear
The one in front is
Likely to be full."

That's not the way I remember this verse by Brand:

If you wish to pass some water
Kindly call the pullman porter
He'll leave a vessel in the vestabule
If the porter isn't near
Then try the platform in the rear
The one in front is
Likely to be COOL.

You're probably correct!

Cheerily,
Charley noble
