Halloween in July?

Yep! Anyone else's 4 yr old talking about Halloween? It's mid July and I hear about Halloween daily. Yesterday, Samuel wanted to be Scooby-Doo. "Mommy, I think I want to be Scooby-Doo for Halloween so we need to find a collar for me." The day before, "mommy, I want to be a transformer--I promise I'll wear the hard mask." Day before that, "I want to be a mummy so I can be VERY scary, no, maybe I want to be Spider-man." I think I've been hearing all of this for a steady two weeks now! Geesh, can you imagine how it's going to be once the Christmas catalog's start arriving?
