Is it Poetry if it Doesn’t Rhyme?

Not a lot of content today. You have to supply the rhyme.

Reminds me of a poem we used to recite when I was a kid:

Mary had a little lamb
It fell into a well.
Mary threw some dynamite in
And blew it all to little pieces about so big.

Another poetry question: Is this a limerick?

A limerick writer named Drew
always ended his poems on line two.

How about this one?

A limerick writer, a Hun,

Enough! I’ll go to my room now.
