Say it quickly several times.

Seventh grade chorus class began with a list of vocal warm-ups for us to practice, such as "rubber baby buggy bumpers" and "What a to do to die today..."  After hearing a radio announcer read lottery numbers recently, I thought of another phrase that we could have used as a warm-up--"lack of the luck of the draw."  It's challenging to say and summarizes what lottery number announcements usually mean for most listeners.
