Some low-level mafia thugs are playing cards...
One of them says, "Where's Joey? He never misses poker night."
His friend says, "Oh, didn't you hear? Joey's dead."
"Awww, that's a shame. How did he die?"
"Well, he went to the doctor last week and found out he had gonorrhea."
"So? Gonorrhoea isn't fatal."
"It is if you give it to the boss's wife."
