So Your Character is a JACKASS....

Optional rule for D&Dish RPGs: If when rolling 3d6 for the Charisma stat one rolls any three matching numbers on the dice (1-1-1, 2-2-2, etc.), the player must make a saving throw or their character is a JACKASS and must roll on the table below. Of course, a JACKASS with an exceptional Charisma score represents a monumental threat to both the adventuring party and the campaign world they share, and should only be run by a very responsible and cooperative player. A JACKASS may be of any class or alignment.

Note: Unless my math is faulty (always a strong chance), this provision will produce the chance of a JACKASS only 1 in 36 times, which, as we all know, grossly under-represents the real-world ratio of JACKASS to non-JACKASS.
