Dibble unmasking as Teddy after the race would be awesome
The Nationals could sell a lot of tickets, with proper setup:
1) Dibble announced a date that he is going to mug Teddy and take over the costume. (Not a day that Strasburg or Livan starts.) Maybe 10 days advance notice.
2) A few days later, the Nationals front office announces that they are NOT going to stop Dibble. They'll laugh and say, "If he's wants to try it, who are we to stop him."
3) In the meantime, the front office sets up the charities for future races, to be announced after the Dibble Mugging. The Nationals could make the contribution, if no sponsor steps forward. It could be $100. Just make some independent event like that force a fair race.
4) The Nationals provide me with seats in the President seating section, for the idea.
5) We all see what kind of shape Dibble is in.
