Writing a limerick is too much work, so I just wrote something for you to recite in your head while doing the HITs:
Oh, OCMP5
When I'm workin' on you, I feel alive
Wearing my hair in a beehive
Oh, OCMP5
WORD!
Limericks are short poems of five lines having rhyme structure AABBA. It is officially described as a form of 'anapestic trimeter'.
The 'anapest' is a foot of poetic verse consisting of three syllables, the third longer (or accentuated to a greater degree) than the first two: da-da-DA. The word 'anapest' shows it's own metric: anaPEST.
Lines 1, 2 and 5 of a limerick should ideally consist of
three anapests each, concluding with an identical or similar phoneme to create the rhyme.
Lines 3 and 4 are shorter, constructed of
two anapests each and again rhyming with each other with the overall rhyme structure of AABBA.
Maybe sober. I'll stick to something simpler like astrophysics or quantum physics.
