Claim a spot by submitting your meme the day/post prior (ie - post meme for day 3 on day 2). In the event of multiple submissions, most upvoted by day's end take it. Tie breaker based on my poor taste.
Apparently it's a real, available item! Also, I thought it'd be fun to decorate the title card around each day's meme. Just giving myself reasons not to do more responsible stuff.
