Some mafia thugs are playing cards...and so 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 gonorrhoea."

"So? Gonorrhoea isn't fatal."

"It is if you give it to the boss's wife."
