You know those figit toys and figit spinners?

Bonus points if it still looks like a figit toy.-- mofosyne, Apr 15 2017 hmmm.... https://ae01.alicdn...oys-Golden-Toys.jpg [mofosyne, Apr 15 2017] [+] connects to the Internet, modifies NPC behaviour on random MMORPG's.-- FlyingToaster, Apr 15 2017 When in some places nightsticks were forbidden, Cops found very large metal flashlights worth taking along.
