I LOVE ThinkGeek! My husband and older kids go through the catalog before every gift giving holiday and make a list! Last Christmas I bought David (my husband) one of the extra powerful green laser pens (he likes to drive the dogs crazy with it

). It was great to use to point out stars and constellations, too. Zack (my 20 year old son) asked for the E-ink watch. We had no idea how huge it would be (he's fairly thin) and the thing was way too big for his arm, but it was pretty cool looking! We ended up sending it back, though. Zack also swears by the caffeinated soap, but I think it's all in his head!
