4.2 - Obvious
I once met a fellow, named Mickey,
Who poured me a drink, rather sticky.
Club soda and lime,
With rhythm and rhyme.
He said it was called a Lime Rickey.
[Editor's Note: theme and topic are like parent and child; you use one to explain the other. In poetry, the theme is often an emotion, a feeling, a sentimental journey from smile to grin to laugh to pleasure. Word play is a way to generate smiles. The format (limerick) is often used to generate grins. The recipe above is clearly meant to make people laugh. The only doubt is about the title.]
