Robin Hood actually gave to the King. Here's how:
Step 1: Rich kid dumps Gold on some random village
Step 2: Villagers have a riot and a big fight
Step 3: The strongest (and the least brightest) gets the money
Step 4: He buys a bunch of alcoholic drinks and gets drunk, causing barfights
Step 5: The Sheriff of Nottingham comes buy, has to confiscate the money by giving it to his Majesty's collector of taxes.
Step 6: Taxes paid, villagers injured, dead, imprisoned, or pregnant; Sheriff of Nottingham gets written off as the bad guy because Alan-a-Dale sings about how great a hero Robin Hood is.
