Don't recall that Hinnant one but that was funny when the adults would play children characters. And not sure if I recall that specific easy reader one but one I saw a lot was when she says, "Easy reader!" excitedly and he says, "Sylvia!" and then she goes, "haha!". Then they sing something like, "One word comes after the other."
Remember the cartoon where the wife says, "George, you drive me up a wall!"
He is sitting in the living room chair and says, "Hmmm?" She says, " I said you drive me up a wall!" He said, "Drive you up a wall?" She says, "Yes!" So he grabs her in the chair with him and starts driving the chair up the walls around the place. When I was little I had never heard the expression so I asked my dad about this skit and he explained it to me.
Then do you remember the cartoon man crawling on a desert weakly saying, "Water... water.....water..." Then it rains and rains and rains. And we see him treading water now saying, "Land....land.....land!"
