Anybody remember, and can point me to, a Ben Stein routine I saw him to once on TV? It was (something to the effect of) “Words that sound dirty, but really aren’t and you can say them on TV”. I believe two of them were “frigate” and “monocoque”.
I don’t remember that, but I do remember a David Letterman Top Ten list of phrases that sound dirty but aren’t. One of them may have been “Shaking hands with President Lincoln.” I’ll try to dig that up.
ETA: That list is on this page: http://artofhacking.com/IET/HUMOUR2/live/aoh_topten1.htm
Krusty: Kent, the young people today, they think comedy is dirty words. It’s not – it’s words that sound dirty, like “mukluk.” [Kent and Krusty share a laugh] Mukluk. You like that? No charge. Mukluk. [laughs] Mukluk …
I was a 4-Her in high school and we had a national level horse quiz bowl team (I know, NERD!!). So during the “tryouts” for the team, my leader asked me “What is Mastication?” She had a great sense of humor, so when I didn’t know, she said “It’s something your mother told you never to do”.
Of course it means nothing of the sort, but I still get a good laugh out of that.
