Funny Joke: A couple was playing a game in bed

A couple was playing a game in bed. The game was called "Guess What I'm Thinking." The wife thought of something and said, "It's big, round, and you can't touch it." 

The husband thought for a moment and said, "Is it your belly?" The wife giggled and said, "No, silly!"

Just then, the husband had a naughty thought and whispered to his wife, "Is it your butt?" The wife blushed and said, "No, not that either." 

The husband was stumped, but then the wife revealed the answer: "It's the moon!" The husband laughed and said, "Well, I was close!"
