Puberty starts in your teens
unless of course you're Greek
Somehow it is in their genes
to start in their first week

By the time they're ten years old
it is almost done
There's no patch left that is bald
and eyebrows become one

and still there is no relaxing
it grows for worse or better
The women all continue waxing
and all men grow a sweater

and some grew hair like horses manes
with reputations great almighty
you might know a couple famous names
like Hairystotle and Hairphroditee
