David Battley. Who he? Well he played the teacher in Willy Wonka who is so obsessed with the golden ticket he ends up using Wonka Bars as arithmetical units, as in "If I have two wonka bars in this hand and two in this hand how many golden tickets might I have?" or somesuch.
Why he? No reason really, I have a collegue with a similar overly prominent lower jaw
