Present for the Birthday Boy!

It's is Sam's birthday on Friday and I am looking for ideas for you guys on what to get him!  He's got more toys than can fit in his box, although another frisbee could be an idea but he just chews and eventually destroys plastic toys.  Thought about another jacket, but he hates wearing the one he has and we fight any time we try to put it on him (he sits down and refuses to move!).
So come on people - all suggestions welcome!!
