Hazel Tells LaVerne: Allusion

Reading this poem, the allusion to the Princess and the frog can be recognized. However, the outcome is much different. The woman kills the frog. What is the purpose of referencing the story to twist the ending in a  modern and less charming style? My only guess right now is that it may have been simply for just humor. However, lost in the usage of improper grammer and lacking punctuation, I'm having trouble determining a theme or message from the poem. Usually when I think of poetry, I think of elegent words from hundreds of years ago that I have to look up in a dictionary to understand their ancient meaning. In contrast, this poem is literally the exact opposite of my stereotype of poetry. My only understanding for the theme of this poem is that its intended meaning probably lies somewhere among its informal nature.
