Limericks are not songs, but you write well.
The rule of a limerick is that the first two lines and the last line all rhyme with each other – the second two lines are shorter and rhyme with each other. The last line is usually a “punchline” of some sort, but not necessarily.
L’lovod Chanukah
We lit Ner revii tonight
The flames are so shiny and bright.
With great jubilation
And much celebration
I sure am enjoying this sight!
