chattering flywheel

chatter, chatter, chatter,
what is this cog to say –
Can anything important
take all day to say?
chitter, chitter, chitter,
what could drive your teeth?
is the oil’s heat divine
or do you merely seethe?
chotter, chotther, chatther
the words growl, low and loud,
stupid, earnest flywheel
when you break you won’t be proud.
