For some reason, Sherwood often tampered with the Berkeley Farms dairy products commercials. The prerecorded announcement included a final line "Farms in Berkeley?" followed by the mooing of a cow. Berkeley Farms had hired cartoon voice expert Mel Blanc to do the cow voice. However, Sherwood would insert a pause after the question, then add something else (often totally unrelated to the commercial), before playing the cow sound effect, which was often distorted. He also would tamper with a familiar cigarette commercial, known for the line "outstanding...and they are mild," by interrupting the words with his own comments or a recording that had nothing to do with the product. Reportedly, advertisers didn't mind Sherwood's actions because it actually called greater attention to their products.
