Butch Patrick on Adam-12

My brother's in town. He's watching Adam-12, the one where Reed and Malloy are working with kids for some reason. A girl tells them that one kid has a gun. A REAL gun.

The kid had dark hair, but I thought for some reason that it might be Jodie Foster's brother, Buddy. He appeared in episodes of both Adam-12 and Dragnet. I googled it and found it was Butch Patrick from The Munsters.

"That's Eddie Munster," I told my brother.

"It is?"

"I think so," I said to make it sound like I hadn't just looked it up.

I didn't recognize Butch Patrick at all.
