How about a _poisonous_ single claw on what remained of the manus, like the
poison spur in a male platypus's hindleg?  Cool!  Watch Spielberg run with
this one!  The Mononykus runs up to a great big prey animal, that
ankylosaur, say, spikes it, stands back while the thing crashes to earth,
and then, not having much by way of teeth, SWALLOWS IT WHOLE.

This could also account for the extinction of Mononykus.
