Just wanted to share a limerick wrote by one Australian lady who has been learning Russian with me in company of another Australian lady for about 3 years. She does write poems in Russian, too (and even sets it to music), but this one would be easier to understand for most of you ;-)
She came up with this one after we talked about limericks, haiku and tanka at one of our conversation classes:
Russian grammar's designed to confuse us,
Verbal aspects and cases just lose us,
Bring on major flusters,
While occasional victories enthuse us!
