Visual joke
Just after WW2 a man walked into a pub like this (right hand pulled up into sleeve)
The barman said - "where did you get that ?"
"Dunkirk", came the reply
The barman pulled hi a free pint
Shortly after, a man walked in like this (left hand pulled into sleeve)
The barman asked him "Where did you get that"
"Anzio" came the reply
Another free pint
An hour late yet another man came in like this (both hands pulled into sleeves)
"Where did you get that?" asks the barman
"Burton's - it's ****** going back in the morning"
