After getting pretty bad luck with the pirates, I went to fight Carla with just seven insults (no duplicates) and had unbelievable luck that got me into world record pace. However, a minute later I ruined the run by accidentally switching to the classic graphics...

If my calculations are correct, considering that Carla's repertoire consists of 17 insults, the odds of getting this luck are 7 / 17 * 6 / 16 * 5 / 15 * 4 / 14 * 3 / 13. That is, 1 in 294.67. EDIT: She never uses the "I've got a long, sharp lesson for you you to learn today" in this version, so the odds are actually 7 / 16 * 6 / 15 * 5 / 14 * 4 / 13 * 3 / 12. That is, 1 in 208.
