Watch out for guys selling monkeys
From the PBS/American Experience documentary Jonestown: The Life and Death of Peoples Temple, forty-some years before Craigslist:
June Cordell, Relative of Peoples Temple Member: "The first time I met Jim Jones was Easter 1953. My mother-in-law, Edith Cordell, had a monkey and it hung itself and she wanted to replace the monkey. So she looked in the Indianapolis Star, and in that Indianapolis Star was Jim Jones's ad that he had some monkeys to sell. So it was through that that she met Jim Jones, and came back saying that he had invited her to church this next Sunday."
In Indianapolis, Edith Cordell wanted to replace a pet monkey and saw an ad in the paper placed by Jim Jones who was selling pets to raise money for a church. "So she went over and she bought 'em—a boy monkey and a girl monkey," her nephew Gene recalled. "Jimmy started telling her about his church." Aunt Edith joined and recruited a number of family members. Gene and his wife became disillusioned after Jones returned from seeing Father Divine and made grandiose proclamations of his own divinity. But Edith and about 20 other Cordells followed Jones to California in 1965. Twenty members of Gene Cordell's family died in Jonestown. Aunt Edith left her entire estate to Jim Jones.
