My parents taught me to never talk to strangers, but they never told me I couldn't buy Christmas gifts for them! If you're overdosed with Christmas spirit, Giftastranger.net generates random addresses across the world so people can send gifts to strangers.
There's probably better ways to spread your Christmas joy, like volunteering or gifting to people in need, but it's pretty awesome to think a complete stranger will receive your gift. Unless you're gifting a bomb, then that'd be pretty unawesome. [Giftastranger.net via Notcot]
