An analogy is an extended comparison. For example, Vitali Klitschko once famously said: Share some quotes using boxing as a comparison, or better yet, give us some of your own. I'll start, with my (mis)attributed quote to Vitali:
I believe Miguel Cotto is an Undefeated fighter, because he lost at a Catchweight and I like to fight my opponents at a weight they are comfortable in. Floyd Mayweather
your expectations for that fight is like my expectations for a woman.you'll be entertained a little but ultimately let down.
I'm not sure who said this but something like: People Play Football, People Play Basketball, Tennis and Golf. You can't Play Boxing.
