Thomas Andrew Lehrer,
Songs and Lyrics — The Professor's Song
“ Yet everybody tells me that my lectures are obscure And I can't think why! Consider, for example, oscillation of a spring The force that acts upon it is a very simple thing It's kx3 --- or kx2 --- no, just kx, I'll bet The sign in front is plus - or is it minus?, I forget Well, anyway, there is a force, of that there is no doubt All these problems are quite trivial if you only think them out Yet people tell me, "I have memorized the whole term through Everything you've told us, but the problems I can't do." ”
