If you got a present, it was probably mailed to you.
Chris: A new pair of paratrooper boots, a bottle of good scotch (probably something like Glenlivet), and a gift certificate for $200 at a music store, so he can get a new guitar.
Becky: A year's subscription to the American Journal of Medicine, a bottle of Grey Goose vodka, and The Big Lebowski on DVD.
Leon: A better DVD player than the one he has now (if he has one now), and good tickets for an upcoming Philadelphia Flyers game. They aren't front row, but they're decent.
Sherry: A stuffed frog, a Borders gift card for $25, and art supplies.
Henry: She's signed Henry up for one of the larger Omaha Steaks packages, so he'll eat more often.
O!Henry: Some good film and a Borders gift card.
Eileen: Claire has decided that she needs to send Eileen and O!Henry to Florida for a while to... um... look at things. The flight package (two round-trip tickets, one decent hotel room in Orlando for four nights) is for February, but it can be postponed almost indefinitely. (It's technically a business trip. Really. She plans on writing this off.) Eileen has also gotten a Borders gift card.
Liz: For whenever she gets back, Liz has gift certificates at a liquor store and a tobacco store near their house.
Yoko: A 1GB stick of RAM (Claire probably just walked into a store and grabbed it off a shelf), a Borders gift card, and a gift certificate at a spa somewhere (for hair and nails).
Kevin: A stone-washed denim jacket (she saw it in a thrift store and automatically thought of Kevin, so...), a three-DVD set entitled "The Best of Corey Feldman," and a Borders gift card for $25.
Caboose: A Wii. Claire had to cheat like hell to find one. She's also thoughtfully supplied sturdier aftermarket wrist straps.
Grif: Two boxes of Ho-Hos. He's still very easy to shop for.
Weird Future Key: The biggest and most hideous marital aid Claire could possibly find. Tradition is very important.
