LOS ANGELES—Patrons of the Trader Joe's grocery store on La Brea Avenue and Third Street broke out into gales of spontaneous laughter when fellow shopper and movie star Will Ferrell made a casual comment about apples. "I haven't had a good apple in a while," Ferrell said in the produce section, causing several nearby shoppers to giggle and nod appreciatively at the overheard remark. "Are Paula Reds any good? I wonder if they're sour like a Granny Smith." Ferrell said that, although he appreciates his fans' support, he really wanted a straight answer about the apples.
