My heart.

The man’s son.

What.

One, two and three.

The man owns a small business with 60 employees. He is signing his name on their payroll checks.

He had left his teaspoon in his cup of tea. When he raised the cup to drink, the teaspoon handle poked him in the eye, temporarily blinding him.

None. He has three sisters.

The man was on an airplane when he fell to his death after opening the door.

3

A bar of soap.

The family still had 12 chickens - 4 dead ones and 8 alive!

Turn the equation to 180 degrees (upside down)
16 = 8 + 8.
