Guys, I've been rolling on the floor reading your responses. Great creativity in explaining your rulings.
I would enforce it as Mike Sears did (see copy below) except that I added my two cents after his repost.
We have double fouls, the down would be replayed. All of the live-ball fouls would cancel each other out, except B2 would be ejected for his flagrant face mask foul. We then penalize the UC fouls as dead-ball fouls and in the order of occurence. Penalize team A coach for his U.C. 15 yards back to the A-20. Penalize Team A another 15 yards for a4's taunt/spike. Half the distance to the A-10. I'm not sure of down and distance after penalty but the ball would be on the A-10 yardline, right?
Would it be 2/35 at the A-10? Or 1/10 at the A-10? I'm thinking 2/35.

Mike, my answer is to replay the down 2nd and 40 from the A5. To get here, I took your UC enforcements and added the PA announcer to it to go another 1/2 the distance from the A10 to the A5. Line to gain is still the A45. (Oh, and Mike, you may need to invest in some black and white striped BVD's for such plays)
And HSWH is right. You should eject the coach for his second UC (since technically he's responsible for the announcer). I would probably conveniently forget this ejection.
Sorry to move us from gridiron war stories to Fantasy Island, but this was a fun one to sort out. Good job.
