Anyone recall what the most trustworthy font is?

So easy back in the 90s or 00s there was a webcomic set at either an ISP or software company where one plot line involved the growing awareness of blogs and one of the employees managing to sign some sort of agreement with some corporate lawyers as, "the representative of the blogosphere." Explaining, when the other characters were shocked the corporate lawyers would buy that claim, that it worked because, "I had a business card saying that in (font name) which is the most trustworthy font. People will believe anything if you put it in that font."

And now I'm sitting here stuck because I don't remember which font it was. Maybe Copperplate Gothic Bold, but that's a guess. This question, which font it is, is going to be stuck in my head for days.
