Stan Laurel and Oliver Hardy reached their creative best with Twice Two where they their usual selves and female counterparts. It seems as though Stan and Ollie have married each other's sister and both think it was a great idea as it cements the relationship of the two.
They might have to rethink the notion as a family dinner at the Laurels proves a disaster. The female Ollie falls into a cake during the preparation. There's also a great gag with simply Stan using Ollie's key to open the front door. I won't say more but I think it's a tribute to both of them, especially Stan the creative one that they could get so many laughs with a simple act all of us but shut-ins do nearly every day.
Of course with the female personas half the credit should go to the actresses who provided the voices for the characters. May Wallace for Stan and Carol Tevis for Ollie perfectly match those familiar bodies in drag.
Offspring from these unions would be called double cousins. Just think what those kids might be like.
