Your wife definitely does not sound dorky. Clanky is giving Mari some extra points just because of her! But, um...I'm afraid that doing voices on the DDoCast is only considered "cool" by the DDo community. Outside of that, she is now officially a nerd like the rest of us.
On the bright side, you now have subject matter with which to blackmail her in the future. On the bad side, she now has somethig to hold over you for the rest of your life (ala Sword of Damacles). Good luck with that you two!
And, now, here's an excerpt from Clankenbeard's Masterwork Theater...
ACT 1: THE BRIGHT SIDE
"I'll be having a makeup party with about ten friends over on Saturday. I need you to serve snacks."
"Great! That will be a perfect time play your DDoCast voiceover to all of your friends at once!"
"Maybe you should go hang out with your buddies at a bar."
ACT 2: THE BAD SIDE
"But I don't WANT to go to the fabric store."
"Remember that time you made me do a voice for DDoCast?"
"I'll get my keys."
