Office supplies have to be my favorite shopping genre.  My dad and I used to spend an enormous amount of time at Office Depot just looking around and these evolution erasers are just the type of thing I would have forwarded to him, to which he would have likely replied “Too cool!”

I am completely impressed with the concept of these erasers!  It looks like you start at Australopithecus afarensis and end up at Homo sapiens all through making mistakes while writing in pencil (to err is human – or at least, it will be.  See? Clever).
