He could be quite amusing actually. He was a French teacher ( a teacher of French, that is, not a teacher who IS French) and one of his favourite tricks was to find a young programme seller and pretend to be a non English speaking French supporter wanting a programme. After speaking fluent French at them for 4 or 5 minutes, with them getting more and more flustered, he'd then say something like "Ok, can I have a programme please?" in his BROAD LANCASTRIAN accent, shove the money into their hands and walk off. Another favourite was asking if they had any programmes left, and if they said yes, he'd say "Well you shouldn't have printed so many then". I suppose you had to be there.
