MentalFloss:心理牙線詼諧雜誌是一本致力於逸聞趣事的雜誌，內容涉及科學、歷史、文學、流行文化等領域，這份雙月刊由五位杜克大學畢業生於2001年創辦，很快就擁有了1萬名訂戶和4萬冊的零售量。

心理牙線（mental_floss）名稱的由來，是取「Dental floss」（牙線）的諧音，為2001年創刊的雙月刊雜誌。該刊網頁在「關於我們」做自我介紹時強調，該刊是給聰明人讀的，但也不能太聰明，因看完之後還得想一下，才會知道好笑的地方在那裡。該雜誌另一項財源收入，是販售印有搞笑諷刺標語的Ｔ恤。根據維基百科資料，該雜誌發行量約八千份。

mental_floss magazine is an intelligent read, but not too intelligent. We’re the sort of intelligent that you hang out with for a while, enjoy our company, laugh a little, smile a lot and then we part ways. Great times. And you only realize how much you learned from us after a little while. Like a couple days later when you’re impressing your friends with all these intriguing facts and things you picked up from us, and they ask you how you know so much, and you think back on that great afternoon you spent with us and you smile.
