“A brick could be used to ascertain the truth. And then logically, a non-brick could be used to detect the lie. What kind of things are non-bricks? Well, anything from blankets to lies. So therefore, a lie could be used to detect a lie, and all this logic makes me want to grab a blanket and lie down—and that’s the truth.

“A blanket could be used to find the Brick of Truth. Many lies will be layered on the Brick of Truth to try to cover it up, but the blanket will cover up all the lies, thus covering up the cover up and thereby revealing the Brick of Truth. And don’t try to steal the covers, because the blanket will only provide warmth to the Brick of Truth. 
”

“A brick could be used to dispel the very same lies that a blanket could be used to cover up. 
”

“A brick could be used to perpetually feed the hungry, stop all wars, educate the masses, and ensure everlasting peace for all populations throughout time. Wait, I’m sorry, that’s not right. I was confusing a brick with a blanket. It’s a blanket that could be used for all those things. 
”

“A brick could be used to keep warm, and a blanket could be used to build a house.”

“A brick could be used as a key to unlock a door disguised as a brick wall. The security in the lock lies not with a one-of-a-kind key, but with a key that looks like hundreds of other potential keys that make up the door.
”

“A brick could be put on the end of a scale, to determine if the other end of the scale holds a lie or the truth. (Hint: The truth is much heavier than a brick.)
