I'd have to agree .. its classical .

About 3 years ago I did see a Ventriloquist where, like this one, The "dummy's face" was identical to the artists face .. The dialogue was what kept me in awe as after a while I had no idea who was doing the talking ..

It was simply called "Adam & Steve" (a parody in itself) .. who were identical twins ..

Keep a watch out for it too ..
