Lecture Preparation Differences

Pharyngula: I'm Beautiful--On The Inside

When a lecture's about to begin
Mr Myers seeks pow'r from within,
and the song that he hums
(done his own way) becomes,
"I've got myself under my skin."

Ere I lecture a crowd I just sit,
for it settles my nerves just a bit
if I ponder my gut
and its maximal glut,
and then think what I plan to emit.
