Peter Arnell was the guest judge of an event-marketing competition on last week's episode of The Apprentice: Martha Stewart. Stewart gave two teams the task of creating an event to market Tide to Go, a new stain remover that comes in the form of a pen. Arnell heaped praise upon Matchstick but had nothing nice to say about Primarius, whose event he called "pathetic" and a "waste of my time." Arnell returned later in the show, as a guest at Stewart's Bedford, N.Y., home, where she feted the winning team with breakfast. ... Rochelle Settle, a receptionist at Colby & Partners in Santa Monica, Calif., flew to Washington, D.C., last week to sing at Rosa Parks' memorial service in front of thousands of mourners, including Oprah Winfrey, Dick Gregory, Sen.

(Settle had sung at his mother's funeral.) The 35-year-old soprano sang a medley of spirituals. "It was a once-in-a-lifetime experience," she says. "[Rosa Parks] was a humble Christian woman who devoted herself to young people." ...

The Go-Gos played, and a remixed Go-Gos video from the 1980s was shown, recut to include shots of present-day models in Nordstrom's clothes.
