A Crying Sham

No dramas at all with the words and the meter's handled pretty darn well, but here's a thought that's guaranteed to send you mad (or sane, given the effect of multiplying two negative numbers). 

In S2 L2 you use "yawn" which rhymes with L1/L4 in the first stanza and kind of got me excited, thinking it was going to be a bit more of an intricate scheme (shut up about the little things that excite me).  I don't suppose there's any chance you could stick an "ung" rhyme in S3 L2, and an "aged" rhyme in the last stanza?  No?  Well.
