Mine was in 2001. I used to post regularly on the message board for the game show The Mole, (sort of an intellectual version of Survivor, and the source of my bobistheowl handle). At one point, I was talking about "the game, within the game, within the game", and I expressed that in mathematical form as:
{ga[ga(game)me]me}
A whole lot of people on the message board misinterpreted that, and thought I was saying that I was gay.
