Hitman 4: Blood Money, several Easter eggs on Mission 8 - Till death do us part

Dancing 47: If you position yourself on the dance floor and leave Agent 47 idle for a minute-or-so, he will start to dance. Hillbilly Fightclub: To the left of the dance floor, you will see a small crowd gathering around a pair of fist-fighting hicks. Providing that you stick to using just your melee attack, you can actually fight the both of them without causing yourself any trouble with the guards. Silver Coin: In front of the mansion (far left; near the water) is a very small, silvery disc shaped object which looks a bit like a coin. Get out a firearm and shoot it. When this is done, men in their boxers will come and give you an applause.
