Public service announcement: If you're going to participate in a contrived marriage proposal stunt on the floor of the MCI Center during a Wizards game, you'd better be 99 percent positive she's going to say "yes."
This woman did not say yes. Her response was to run off the court, into the tunnel.
Come on, baby! You could at least pretend you accepted his proposal in front of the thousands... er, hundreds of people in attendance, and then tell him later that you think getting married might not be a good idea. So that he's not completely humiliated.
Link props to Swamp City.
