It's a Poem! It's a Riddle! It's two, two, two mints in one! Depending on your perspective, I'm getting better (or worse) at devising bad riddles. Give this one a good think... it might come to you. Good luck:

Bat guarded my City;
I'm also a Ram.
My ball summons ducks
Can you guess what I am?

Here is the ANSWER.



Bat Masterson lived in Dodge City, Kansas, where he served as Ford County sheriff.
The Ram is the symbol of the Dodge automobile line.
The heaving of a dodge ball would summon "ducks" from those trying to avoid being hit.
