50/50 Joke
At the Ruby during one episode, Karen remarks to Davis and Lacey that the odds of a riot in Dog River are 50/50 - either it happens or it doesn't.
A follow-up joke could have been Davis explaining this to Wanda at Corner Gas. Then Wanda could have told Davis to buy some lottery tickets, saying "Your odds are 50/50 - either you win or you don't". To which Davis would say, "All right!".
