Commando Friday occurs every Friday on Twitter. It’s a day for you to go commando (no underwear). And if you’re on Twitter, you can prove it by tweeting your Commando Friday proof with the #commandofriday hastag and it’ll appear here.
These pics are automatically gathered when the #commandofriday tag on twitter is used with TwitPic or yFrog. Also check out CommandoFriday on Twitter. Let me know if you have any other requests/suggestions.
