@Nooblette,
Look back a couple of hundred pages until you get to December 2008. Or look back in the Lenny Conundrum to #290.
Each deposit at the bank was 3 days worth of the Advent Calendar's NP awards. The question asked for the 6th deposit, I think it was, which meant we needed 18 days worth of the Advent Calendar. However, the Lenny came out on about the 13th, so we had to wait until midnight Monday night to find out the total of the 6th deposit. They have 250 submissions in the first 20 seconds after midnight.
