T.s. Eliot said this quote

The Pekes and the Pollicles, everyone knows, Are proud and implacable, passionate foes;It is always the same, wherever one goes.And the Pugs and the Poms, although most people saythat they do not like fighting, will often displayEvery symptom of wanting to join in the fray.And theyBark bark bark bark bark barkUntil you can hear them all over the park.
