Further in my collection of posts you won’t find in a coursebook, and nastiness we could do without (if it weren’t funny): I’ve just finished writing a quiz on using future tenses, and have saved the most sexually incorrect joke I could find for you.
“And you’re drunk.”
“Yes, but in the morning I ________ (be) sober.”
What do you think, is it also incorrect in terms of gender? I mean, the drunk person could be a woman.
