I'm learning SAS, and I'm reminded of xkcd comic number 1172, because I was hoping to use my computer disconnecting from the internet and burning down to catch errors (in my case, I was using "if A then do this, else if B then do this, else 1/0" when all possible cases should be in A and B). I suppose it's good that I learned this now rather than later on when a division by zero would be bad and I'd have no idea that my very bad division by zero won't be caught, but still, sometimes you want a quick and dirty "disconnect from the internet and burn down"
