Sexed Ed

there should be a rule
a horse is a mule
when it's missing critical parts

this rule is maintained
when horses are trained
in racing and other fine arts

but this one, this Ed
got up out of bed
and thought: "I think something is missing"

he later discovered
they're not in his cupboard!
the ladies rejected his kissing
