I get it, very amusing.Not for serious critique though, so I'm just going to shift this to mild. You might like to familiarise yourself with the posting rules for each forum.
What I like about this little poem is its self-awareness, and the idea that the five lines of a limerick is just too verbose. I confess I was tempted to refute your limerick claim before I actually read it -- and that temptation made the realisation of the poem's purpose all the sweeter.
I would have liked to see this rendered in slightly more limerick-y meter, but that's a small thing.
It could be worse
