“My children, jump, run and play! Make all the noise you want, but avoid sin like the plague and you will surely gain heaven.”
-- St Don Bosco
My interpretation, in regards to this thread: St Don Bosco's point is that having fun is better than idleness and boredom, which can often lead to temptations. Occupy your mind (in moderation) with entertainment and it's harder to sin. Thus, you are using entertainment as God intended (i.e. to relax and refresh the mind, after the day's work and duties are fulfilled).
