A little mousey man he was
 With board, and chalk in hand;
And millions were awestruck because
 They couldn't understand.
Said he: 'E equals Mc2:
 I'll prove it true.'

No doubt you can, your marvel man,
 But will it serve our good?
Will it prolong our living span
 And multiply our food?
Will it bring peace between the nations
 To make equations?

Our thanks are due no doubt to you
 For truth beyond our ken;
But after all what did you do
 To ease the lot of men?
How can a thousand 'yous' be priced
 Beside a Christ?
