On July 18, 1995 — Dave Andrews, public address announcer for the Abilene Prairie Dogs of the Texas-Louisiana League, is ejected from a game after Abilene manager Charlie Kerfeld is given the boot. Andrews proceeds to read a commercial for an eyeglass chain, infuriating the umpire. Andrews claims it was coincidence, but is still fined $50.
