throttle got stuck???

[M900]

I was off to work today and when I pulled out, the revs jumped up and I couldn't back it down.  I thought the throttle was stuck, but twisting it back did not work, nor did pulling the bar end mirror away and tapping on it do anything...  I also fiddled with the choke -- no go.

Any ideas?  the Monster's a 96 M900 with carbs.
