On Saturday, when Adam Rosko (Capt. James T. Kirk) and Jaime Kirk (secret assassin Thelev, and yes, you can guess why Jaime's parents named him what they named him) started fighting, an unleashed dog raced the stage barking. Hackles up, concerned: the dog's body language was Oh no! They're fighting! Stop it! The audience cracked up. The owner ran onstage, dragged the dog off and out of the way, then sat her down and kept her in place the rest of the show. Rosko and Kirk continued their fight, Kirk went to the stage as planned, Rosko played wounded as he should, and when he called for security to help him he added "and I found the ensign's dog." Which cracked up the audience again. Then post-show I found that Jesse Graff, who plays Spock, had already wondered what would happen if a dog went onstage, and because he loves the latest Star Trek movie so much, he'd decided he'd use that moment to say "Tell Admiral Archer we've found his dog!" But Graff wasn't on stage when that happened. But! He was ready if he were!
That said, LIVE THEATER SHOULDN'T INVOLVE A DOG (unless Billy Shakes wanted one) SO KEEP YOUR DOGS LEASHED, PEOPLE. SHEESH.
Do something positive when you can, OK? Give a nice shoulder rub to someone who can use it, help somebody with an errand, kiss or do more with someone who likes when you do that, hug... nice and happy stuff is possible!
