Once upon a time, we had a regular who would spend the entire 90 minutes berating the players. This guy (never knew his name, and he'll be dead by now) made David and Dennis look like Sunday School teachers.
One afternoon, he'd been giving the whole team, and Lenny Dickinson in particular, dog's abuse. About an hour in, a visiting player was receiving treatment just in front of this guy, when Lenny jogged across to the touchline "Oi bigmouth, where do you work ?" bellowed Lenny.
"Budenbergs" replied the startled heckler.
"One more word out of you, and me and the lads'll be down there Monday and shout rubbish at you for 90 minutes while YOU'RE trying to get a job done !" with which Lenny trotted away to the applause of about half the popular side who'd heard it all. The loudmouth was subdued for the rest of the afternoon.
A couple of games later, he was starting his tricks again. Lenny wandered across at the start of the second half and simply glared at him. The guy walked out of the ground, and we never saw him again.
