I was asked this by a 10 year old and was completly bamboozled for a while, but eventually riddled it out. What am I? You throw away the outside Cook the inside Eat the outside and throw away the inside.
You have to shuck the corn so you throw away the outside. You have to cook the corn which was the inside You eat the corn of the cobb (the outside) then you throw away the cobb (the inside)
I didn't know you were joking. You would be suprised at how many people wouldn't "make the connection." I have been called Mr. Obvious (my uncle never lets me forget it either) many times, I have a very literal thought process, what I see is what I understand.
