S1·E36 Jackpot for the Daltons
Aired October 27, 2002
Synopsis
Lightning renders dumbo Averill smart enough to lead a Daltons escape and evil, seizing command from Joe and aiming to rob Fort Knox. While Lucky Luke sets chase, the lightning wears off, so Joe goes looking for more electricity to reproduce the effect, but can only recur to a rain-dancing Indian medicine-man.
