The Fickleness of a 6 year old

Ok. I have to laugh. My son originally told me he wanted a Spiderman party for his 6th birthday party (this Saturday). After I sent out the invitations, he got on to me and said "no, I want a POWER RANGER PARTY". So, I went and got a power ranger (Dino Thunder, per his request) pinata and goody bag fillers. I had already gotten spiderman goody bags, so he was stuck with those. I took him tonight to order his birthday cake. So, what does he get? Neither spider man nor power rangers... he got Yu-Gi-Oh! Only 5 days to go.. wonder what else he'll throw in?
