Throw a drunkard in a cage with a tiger and some spikes and the tiger will have the time of its life playing with them! Think of all the tiger play time possibilities!
If you aren't the tiger, watching it play is a little like watching someone's head get cut off with a guillotine (ぎ). In fact, you don't want to watch it play at all anymore.
