Sunglasses, an electric toothbrush, $200 gift voucher, cash, and the new Raymond E. Feist book.
Much to both my and my father's amusement, my dad gave me Tiger Woods PGA Tour 10 for PS3 and I gave him Tiger Woods PGA Tour 10 for Wii - we both had the idea that we could play it together, like we used to with Jack Nicklaus 4 on the Mac and Golf on the Game Boy.
Since he's not quite finished recovering from a shoulder operation my dad won't be able to play the Wii version for another few weeks, but we've just spent two whole days playing the PS3 version together (it's almost 10pm on the 26th as I write this, so no we didn't open presents early)
