Once an alien came to earth, he didn't know any English.
He was walking along one day, when he heard someone say the word, "Yes!" Loudly.
He went to a restaurant and heard a waiter say, "Forks and Knives,"
He went to the candy store and heard, "HE STOLE MY LOLLIPOP!!!!"
A little while after there was a murder, the police came and interviewed him.
Police: Did you kill this man?
Alien: YES!
Police: What did you kill him with?
Alien: Forks and Knives
Police: Why did you kill him?
Alien: HE STOLE MY LOLLIPOP!!!!
