Deke & Gretchen's Sister

I know, I know, you're probably saying to yourself, "I didn't even know Gretchen had a sister!" Neither did I until Deke introduced me to her while Gretchen was out of town for the weekend. (I think he had something in his left eye, because he kept blinking it.)

Granted, it has been a while since I've seen Gretchen, but the resemblance is uncanny and it's obvious Deke loves the sister as much as he loves his wife, what's-her-name.
