A mate of mine knows a season-ticket holder at Arsenal who told him this allegedly true story recently.
His season-ticket last year was an absolute plum seat half way up the Highbury main stand close to the half-way line. In other words, a TV camera style view.
Anyway, after the first few games of the season it became apparent that despite all the home games being sell-outs, the two seats on his left were always empty. This continued until just after Christmas when all of a sudden a guy and his young son appeared there.
After a few weeks of sitting next to this guy and his son, he decided to ask if the guy knew why the seats had been empty for half the season. The response is legendary:
'Yeah don't even go there mate. The wife bought me and my son a season ticket but decided it would be a nice idea to give us them for Christmas. I was **in' raging!'
