If Peter was a teacher, he would be doing more of a disservice to his students than anything else. Not only does he not have the time to make lesson plans, grade hundreds of tests and assignments, or even reliably show up to school everyday; he also doesn't have a degree in education (which is a necessity to becoming a teacher in most places). I think people need to remember that a brilliant intellect has no correlation with teaching skills, and a flakey guy like Peter (despite having all the right reasons for it) is exactly the type of person students DON'T need.
