Most expensive: My DSis12 (I'm 9 years her senior) asked for an iPhone. Luckily I got a new one and was planning on giving her my old one anyway lol.
Weirdest: hmm....this is rough....my DBF asked me not to spend a cent on him this year....that's all I can think of....so far it's worked out great, since I found some AWESOME freebies online :-p
