People giving oratory with the express intent of motivating the audience can often be heard requesting levels effort of greater than 100%. They are not in error (as is so often thought). All students of the most advanced and complex mathematics are required to give talks during a two year enforced sabbatical. The subjects are often topics such as screen writing success and pyramid selling to remind them how the non-academic world functions - they just can't help throwing a few mathsy "in" jokes in that the rest of us hear as meaningless buzz words.
