No More 11-Hour Shifts

via boingboing

I was thinking today while working about making change. I had run out of fives. I was thinking about how many ways you could arrange the people already in line so that I could make the right change for them (the right change being not handing out more than 4 ones). I figured things out when it got slow. Now that I get home I recognize the problem (Catalan numbers). Friggin' Euler.
