when i was about 20 i stood outside top man on fargate waiting for my girlfriend who was inside , there was a large group of 16 -18 yr olds outside and feeling a little intimidated i nonchalently leant back into a side window that wasnt there!!!!, and fell flat on my back knocking the open display area flying ,dummies , shoe stand , the whole thing !!!!
it was just like the del boy scene in the yuppy bar !!, i simply got back up in about a second flat , as you do , and ran , it took my girlfriend ages to find me , and her first question was "wot were all those kids laughing at when i walked out of top man ?", my reply was " dunno summat stupid probably" and left it at that !!!
