Question

There once was a man whose head and hands worked together to solve problems. One day, the man's head was very cold. The head asked the hands to help. The hands came up with a plan and placed a cap on the head. The head said to the hands, "Way to put on the old thinking cap!"

What is humorous about the statement that the head made to the hands?
A.
The head points out that the thinking cap is "old," which is probably meant to embarrass the hands.
B.
Hands and heads cannot really talk to each other, so anything they "said" would be humorous.
C.
A "thinking cap" is a metaphor for making a plan, and a cap is a hat that would keep the head warm.
D.
The hands cannot think without the head's help, so the head is being silly and rude to the hands.

Answer 1

C

It's a pun: "thinking cap" normally means a figurative cap you "put on" to think, but here the hands literally put a cap on the head to keep it warm.
