When the superbowl hats came out there were these footballs that admins were randomly giving out. You can throw them around and anyone can pick them up. I was just wondering if it was going to be sold or something?  

Nup  

They spawn at the onnet shop, staff don't give them out, they are Temporary NPC's. meaning they fade away over time. i wish it was a furniture item(that you couldthrow), that would be sweet,  

You can't keep them. They have a respawn time after being on the ground too long. There's a glitch where if you have two footballs and keep throwing them in one place you can create a fake football. The fake football is normal until it is thrown. It disappears upon contact with the ground. I think this would make a nice furniture item because you can make a lot of games with this.  

This item was already made 1-2 months before the Superbowl.  

lol!
