Poor Shakespeare

A sonnet is very hard to write
even if I spent really long time
I wouldn't get the meter right
neither would I be able to rhyme

Does swell rhyme with shell?
Does guitar rhyme with star?
Does hell rhyme well with bell?
Does bar rhyme with car or jar?

What is a iamb? Is it maroon?
Second syllable should be stressed
Can a iamb also be full moon?
Verse foots make me very stressed

Calling this a sonnet would be lying
Poor Shakespeare in his grave is crying
