A couple o' limericks
There was a guy named Little Billy T,
who missed every damn possi-Billy-T
of upgrading his head,
and that drove him all mad -
from a-Billy-T to de-Billy-T.
One inventive street cop in DC
Felt an urge to find WC.
As he sat on that stool,
he invented a rule...
Now they all have to follow, you see.
