There was a joke back in the day and in the 2nd leg at Ibrox, Eintracht score and one wee German in the Rangers end celebrates the goal and then immediately shuts up what with being surrounded by bears.
A wee Rangers fan next to him says just celebrate, you're here to support your team. There's nothing wrong with that.
Eintracht score a 2nd, a 3rd a 4th, a 5th and finally when they score their 6th the wee Rangers fan whacks him across the napper with a bottle.
The bloodied and dazed German cries out; 'What was that for? You said it was okay to support my team.'
The wee Rangers fan says; 'That's not for the football, that was for bombing Clydebank during the war!'
Was probably funny at the time.
