As for Mr Bean, I've shown students the sketch on DVD where he opens the wrong envelope in the exam room (only revealed at the end), when taking the Trigonometry or Calculus exam. He tries various and very funny ways to copy another student's paper. I use this to explain about exam procedures, plagiarism and general unethical behaviour. It always gets a good laugh from students, but the point is rammed home.

Thats a classic clip, I've shown that too, lol.
