Improve your spelling! Amaze your friends! Time for more fun with mnemonic devices:
anoint: to anoint is to apply an ointment or liquid to something, so think "an oint(ment)" and you'll avoid the misspelling "annoint"
embarrassment: the R's and the S's trip folks up; remember that the embarrassment is extreme enough to accept doubles of both (this is similar to my tip on spelling "accommodate")
harass: this is another word where the number of R's and S's causes confusion; think of "sexual harassment" and the "ass" in "harass" (you'll never forget this one again)
