The best Christmas presents we gave this year did not come from huge piles of money (well, a few did). Most of the really good ones were a few things we picked up at a shop called Archie McPhee's:
A gummy banana slug and various other gummy goodies including gummy steak and gummy tapeworm were a big hit among my brothers. I still haven't gotten any reports on whether they actually tasted good though.
A toy gorilla (similar to the one shown) was a big hit for my youngest brother. He liked it much better than the book "Who pooped in the park?", our other present to him.
A brain jello mold. If you use their recipe (on the back), the brains will come out all gray and slimy and perfect.
