Interesting - and telling - that a man promoting a product supposedly conducive to sleep does not know the difference between "lie" [rest or recline] and "lay" [put or place (something)]. "Lay" requires an object; "Lie" does not have an object.
"Laying" (putting or placing) your head (object) on a pillow.is correct. But simply "laying" (resting or reclining) on a pillow is incorrect. You "LIE" on a pillow - you do not "lay" on a pillow (no object). That this man does not know the difference does not mean he's dumb.
It means he's ignorant. (Ignorant means you don't know - but could learn.
Dumb means you can't know -you don't have the capacity to learn. We will have to wait - and watch future commercials - to see which one this man is.
