Who remembers Fortress Upton Park? No, me neither.
And, yet, after another depressing capitulation, this time against Manchester City, the airwaves and message boards were full of disgruntled West Ham fans who could not recall their team rolling over like this at the old place.
Shipping five goals to City and Arsenal at home in the same season is being blamed on the move to the London Stadium, as if the best teams once shivered when imagining a trip to east London.
Happily, there are record books for the times when memories fail, so we can see Manchester City lost once in seven visits to Upton Park in the period from March 1, 2009.
