Minecraft wiki entry for Things_to_do_when_bored, associated text: This is best done in the superflat map creative mode. Fence an area, summon a bunch of mobs (don't summon flying mobs or mobs that are immune to fall damage) with spawn eggs, equip a fishing rod and fly as high as you want, but don't fly more than 34 blocks off the ground, and then start fishing for these mobs. If the fishing rod hooks a mob, "release" it and make it fly. You could also organize a race with your friends to see who is the best.
