A Panda walked in to a pub, ambled over to the bar,took a customer's sandwich; ate it-pulled a gun, shot the man dead, and left.
The barman was agast; he shouted 'OI, come back ! You can't do that'
'I can... and I did' said the panda ' I'm a panda-look me up in the dictionary '
The barman and his customers got a dictionary, opened it- and looked under the word Panda...
it said, 'Panda- eats shoots and leaves'
