1. A man and his son are in a car crash. The father is killed and the child is taken to hospital gravely injured. When he gets there, the surgeon says, 'I can't operate on this boy - for he is my son!!!' How can this possibly be?
Solution
The surgeon can not operate on her own son; she is his mother.
2. A man and his wife raced through the streets. They stopped, and the husband got out of the car. When he came back, his wife was dead, and there was a stranger in the car.
Solution
The wife was about to have a baby. They drove to the hospital. The husband left to get a wheelchair, but the baby was born in the meantime, and the wife didn't survive the birth.
