I periodically cut the karma total on my account. Now I think I should set it to -1.

  (when (is (karma "dang") 65535)
    (add-karma "dang" -65536))

Edit (after skimming the thread): here I was thinking my joke was original...I forgot who I was dealing with here.

I was going to suggest that perhaps it was already rolling over.

Maybe do a signed short, just for you instead?

Just make sure you don't use C anywhere in the stack, because overflowing signed integers is undefined behaviour.
