"Ha, Nazi, Schmazi," says Wernher von Braun

Gather ’round while I sing you of Wernher von Braun,
A man whose allegiance
Is ruled by expedience.
Call him a Nazi, he won’t even frown,
“Ha, Nazi, Schmazi,” says Wernher von Braun.

Don’t say that he’s hypocritical,
Say rather that he’s apolitical.
“Once the rockets are up, who cares where they come down?
That’s not my department,” says Wernher von Braun.

Some have harsh words for this man of renown,
But some think our attitude
Should be one of gratitude,
Like the widows and cripples in old London town,
Who owe their large pensions to Wernher von Braun.

You too may be a big hero,
Once you’ve learned to count backwards to zero.
“In German oder English I know how to count down,
Und I’m learning Chinese!” says Wernher von Braun.
