Nearly Past Its Wear Date

This joke is from the early '60s, a time when there still were words that you wouldn't use, even with friends, if women were present. But women were being liberated, and using such words was edgy, and increasingly allowable. To appreciate the joke you'll have to imagine yourself back in that time.The joke is delivered in the first person."I heard a really great joke the other day, but, uhh, it's got some strong language in it. But it's too good not to tell. So when when I come to the four letter word that means excrement, I'm going to say 'Shoo shoo' Okay?"Teller checks with everyone (especially the women if tell is a man) to make sure it's okay."Now for the four letter word that means sexual intercourse," I'm going to say 'Foney foney' OK? (Checks)"And for the four letter word that means a man's member, I'll say 'Papa' OK?""And for the four letter word that means a woman's genitals, I'll say 'Tweet Tweet'. Got that?""Everybody got it?"Now the teller checks to make sure everyone has the code:"Excrement?" Wait for or prompts the answer. 'Shoo shoo'""Intercourse?" "Foney foney""Male member?" "Papa""Female genitals?" "Tweet tweet.""Okay, ready?"Everyone waits for the joke that's "too good not to tell.""So one day these two cocksuckers are walking down the street...."The first couple of times I told the joke it went over really well. The next time I told it, when I got to "For the four letter word that means sexual intercourse..." one of the women said "You mean fuck?" That was the last time I was able to tell that joke. Today I can't imagine getting through the checking phase without someone saying "the real word."
