It's always the period of the game with the worst atmosphere. It's absolutely dead for 5-10 minutes after half time every game. The weird thing is, regardless of how hard it is to get the crowd going in those early moments, as soon as people see a squirrel they go absolutely nuts! The players didn't see it but I bet they wondered what the crowd were whooping and hollering about.
It's because of the amount people who leave 5mins before half time and take the same amount to come back after half time for a beer etc... people whine constantly about people leaving 5mins before the end of games but never mention the ones leaving 5mins before half time and coming back late.
