for goodness_sake; do
be_good;
Not to be a stickler (cuz C++ isn't either), but wouldn't:
for (goodness_sake, !naughty_list(self), jolly++); do
be_good();
be a more efficient solution? Sure, you COULD be_good() in an infinite loop, but it's more fun to exit the loop just as soon as you drop off the naughty list (presumably onto the nice list). Excessive Jolly contributes to global warming. Possibly we should consider a buffer of a few jollies however, as you don't want to be bouncing back and forth between the naughty and nice lists all the time, a hysteresis condition. It might also be worth considering whether be_good("Puppy") carries a different increment than say be_good("Jerk in Hummer that cut me off in traffic").
Data entry is still largely manual, and elves have tiny hands so typing is rough for them.. serious issues with Carpal Tunnel. The section of the naughty list that pertains to me alone requires a staff of ten elves, a gnome, and a Bumble (cuz they bounce). Image the labor costs alone.
On the plus side, Santa's in final negotiations to replace Homeland Security.
