Got $3 just lying around? Well, good news then, because Saints Row IV has a new DLC pack available, titled Pirate's Booty Pack. That can't possibly be a reference to Assassin's Creed IV, no way.
Like all other Saints Row IV costume packs, Pirate's Booty is priced at $2.99, and includes both weapons and outfits for your Saint. The pirate-themed pack does, in fact, let you equip hooks over your hands, and yet you're still able to dual wield. I've no idea how that could possibly work, but this is Saints Row, and Volition ain't gotta explain squat.
In addition to hook hands, you can also equip peg legs, eye patches, flintlock weapons, and a Deck Swabber outfit, then climb aboard the Scallywagon. Seems appropriately ridiculous.
The Pirate's Booty trailer shows off how it all looks. You can also see the Super Saints DLC below.
