Two Comparable Contrasts

what i say about Tim Extends to Solemn Kim Starting with moustache grim and two eyes oddly dim; Two Voices for God’s Hymn Happy to uplift Him…. But I think Tim is slim And Kim rather The Plim, Tim following his whim Prepared to challenge Kim And even rubbish him! Kim fills cups to their brim And Tube judges by Rim, Tim, The One who can skim And comprehensions trim… So, they also contrast, When one lets one’s look last.
