todo.csv

Move with Lil to the black mountain hills of Dakota
Lose Lil to Danny
Get hit in the eye by Danny
Walk into town seeking revenge
Book room at local saloon
Check into room and read Gideon's bible
Drink too much gin
Overhear Lil and Danny in neighboring room
Burst into neighboring room and declare a showdown
Get shot by Danny and collapse in corner
Visit doctor
Return to room and read Gideon's bible
Sing along! D'do d'do d'do do do d'do d'do d'do
