Depends on the enemy. If it's just a Keese, I just slash at it until it's dead. If it's a boss, I take the more defensive side, and ready accordingly for the battle, although it depends on the easiness- level of the boss.
But with toying them... I just run to a spot where they can't come, but are still in my range of view, I just take my bow and shoot them while they are running around looking stupid. The most best way to do this is in TP, while coming from Kakariko, and heading to Hyrule Field, there are those Bulblins atop Bulbos. When you enter the field you notice there's a huge pit leading to a bottomless chasm. All you need to do, is to trick the Bulblins atop the Bulbos to the other side of the pit, while you run to the other side, and then shoot them with arrows, haha, they look just priceless running to the pit! BUT, leave a one Bulbo left. Go behind it and lure it to the edge of the pit, then slash at it with your sword, and watch it run to the chasm, I'm telling you it's HILARIOUS XD
