Raised as an only child after big brother Mike departed Oklahoma for college back east, Benjamin "Benjy" Doonesbury had a distinctly post-seventies teenhood. A bitter spiked-out punk rocker, he changed his name to "Sal Putrid" and only reluctantly attended college at Walden, referring to his Reagen-era peers as "the class of the living dead." Making matters even less bearable, his roommate was Trip Trippler, an irrepressible preppie and Navy ROTC member.
A mid-college change of mindset and a professional name change transformed him into Dr. Whoopee, safe sex rep, delivering quality condoms to dorm rooms. The business boomed and went national, making Dr. Whoopee a national brand, and leading to the founding of the Institute for Immaculate Contraception, aka Whoopee U. With offices in the Trump Tower and Honey Huan as CFO, Whoopee Enterprises also launched a chain of high-end boutiques, and Sal hosted a popular sex-ed TV talk show for teens, "Ask Dr. Whoopee."
Benjamin has not maintained close relations with his brother and extended family, and now lives in Florida. At the funeral of his mother Daisy "The Widow" Doonesbury in 2011 he was proud to remind everyone that he was the youngest Dr. Whoopee sales manager in history.
