whenever I take out money from the bank I sort it out. well I count it first then sort it out. I do it like this.......  (since we have newer lookin' money here) newer 20's then older lookin' 20's, newer 10's then older lookin' 10's, then newer 5's then older lookin' 5's and the ones last. I like started doin' it not that long ago and been doin' it since. weird maybe?
