Mini corncob?

This thing literally came up overnight! Is it a corncob? Does it mean it's been pollinated?

(Edited to add)
After some research, I've realized that is not a corncob :(
As blackstarjewelry picture shows, corncobs actually come from the side of the plant. So this thing coming from my corn is the baby version of the golden stick thingies (nice vocabulary!) that you can see in tomsch picture.
