Mary Stiggler was a sing-song ukulele comic that hosted "Gravy Sundays" in Echo Park. When she changed the mic to a 1-item minimum, the comics left.
Jeremy Duff was the owner/host of a number of shows at The Nickel Bag in Santa Monica. His burlesque show was quite popular. When an open mic was added to follow the ladies, the theater was promptly torched to the ground by its rabid fans.
Ruth Martin was the owner of Ruth's Coffee in Long Beach. She reluctantly allowed an open mic to take place until an inordinate amount of comics used her powder room without purchasing anything. She was known for her hundred-yard glare.
Peggy Turner ran 3 successful bringer shows out of a black box theater in Hollywood. She was frequently drunk during her sets and promised extra stage time in exchange for forbidden pleasures. Thankfully, she stepped in front of a carriage and was trampled by a horse.
Ronald Scott ran the longest running open-mic in Los Angeles, a whopping 27 years. His alcoholism and jealousy towards successful comics lead to a bitter end. He was the first man to drop the mic, after firing a pistol in his mouth.
