Get a zombie villager and put it in a cage to were you can hit it but it can't get out. Then get a 'Splash Potion of Weakness' and a golden apple. Throw the potion on the zombie and then use the golden apple on it. It will take about 2 minutes but the zombie will turn back into a villager.
(Creative) Go to controls make a button for pick block and put the item in an item frame or block on another block a drop and then pick block it.
