William Shatner Medicare bad edit

As if the deluge of these insane commercials wasn't bad enough, pay close attention at about the 1 minute mark. When ole Bill is listing the three ways, when he gets to three, there's a bad edit so it sounds like he's saying three twice

I think Shatner (or "The Shat" as I have just now decided to start calling him), ad libbed the four finger thing and they liked it, so they kept it.

Possibly the same thing occurred with Jimmy "J.J." Walker and his "MUNN-NEEE" tag line.

I think they like these former celebrities ad-libbing things that differentiate their ad from all the others in order to make it less likely for people to just tune them out.

I have trouble doing the Vulcan salute (🖖). I can do it, but I have to work at it a bit. I heard years ago that not everyone can do it, similar to the ability to curl one's tongue.

Maybe it was a joke? Notice that when he says "three" the first time, he's holding up four fingers. Then he catches himself, pushes one finger back down, and says "three" the second time.

I bet there's an outtake somewhere where he pushed down three of the fingers, leaving a particular one up... 

That don't impress the ladies.  But the Vulcan Butt Pinch does...
