Limerick competition for nitpickers

From the Annals of Improbable Research:

2011-04-07 Apes, Lice and Prehistory Competition

Apes, lice and prehistory inspire this month's limerick competition. To enter, 

compose an original limerick that illuminates the nature of this report: 

"Apes, Lice and Prehistory," Robin A. Weiss, Journal of Biology, 2009, 8:20. 

<http://jbiol.com/content/8/2/20> 

The author, at University College London, reports:

"Molecular phylogeny indicates that human pubic lice diverged from gorilla lice 

as recently as 3.3 MYA, whereas the chimp and human host lineage split from the 

gorilla lineage at least 7 MYA. Thus, it seems clear that humans acquired pubic 

lice horizontally, possibly at the time of the Pthirus species' split and probably 

directly from gorillas."

RULES: Please make sure that: 

(1) your rhymes actually do; and 

(2) your poem is in 

classic, trills-off-the-tongue limerick form.
PRIZE: The winning poet will receive (if we manage to send it to the correct 

address) a free, and probably lice-free, hi-res PDF issue of the Annals of 

Improbable Research. Send your limerick to:
