Chlamydia, you grumpy cow!
You're twice as grumpy as Sarah the sow.
Half as happy as Jennifer hen,
But ten times better than all the men !

Chlamydia, Chlamydia,
we never will get rid of yer.
A fixture in the draughty barn,
giving us milk and a gossipy yarn.

Have some grass and Chrstmas cake,
have a snooze and then awake,
to a surprise picnic on your floor,
then you can be a grump once more.
