mommy's balloons!

A kid was taking a shower with his mom and asks, "what are those things on your chest?" Not wanting to answer she changed the subject. The next day the boy went up to his dad and asked "What are those things on Mommy's chest?" he replied "They are balloons so when Mommy dies they will inflate and she will float to heaven. A couple weeks later the father comes home early and his son runs out and says "Daddy, Daddy, Mom is dying" the father ask "what are you talking about?" "Well, Uncle Harry is blowing up her balloons and she's yelling 'Oh God I'm coming'"
