A man embarked on a questionnaire game. He kept asking the same question to whomever he found. The answer each time was different.

Can you guess what the question was?

Two brothers were watching a horror film on video late one night. One brother dozed off and dreamed that he was being chased by the crazy man from the movie, who was trying to kill him. In the dream, he hid in a cupboard. There was no sound except his heart pounding, and he had no idea where his crazed captor was. He was terrified!

The shock at that tense moment was enough that the sleeping brother suffered a massive heart attack and died instantly. True or false?

She closed her door and called security asking them to apprehend the man. What made her suspicious of that man? He might have been genuinely mistaken.
