Another Coffee Story

When Ivan went out, he noticed the coffee pot was half full.  When he came home, the coffee pot was still half full.  So he decided to make another pot.  He took the coffee pot off the burner and poured what he thought was old coffee down the drain.  But he noticed that something was funny.  The coffee was still hot.  Then he realized that Barb had just started another pot.  The half full pot was new coffee which he had just poured down the drain.  When Ivan told Barb what had happened, Barb was amazed he hadn’t noticed the difference between old cold coffee and new hot coffee.
