Was on a school trip in Germany once and this awesome teacher Clive came with us. We went on one of those road trains round the city to see the 'sights'.
Well all the other caradges with our lot were just sitting there bored to death while we were all messing about and joking in ours, Clive came in ours with us.
We notices that everyone was carrying rucksacks in this city so we started shouting RUCKSACK out the window every time we saw one. Clive is about 70 years old (he's retired from teaching but came with us anyway) and was joining in with the shouting lol.
Then I began to press my face up again the window and pull faces at people (childish I know) and everybody I was doing it too was laughing. Well then Clive tried it and these two women looked REALLY shocked and stuck their middle finger up to him ^-^ Heheheh
Twas fun.. I'll have to find some pictures
