LOS ANGELES—After several minutes of heavy skepticism, television star and compensated product endorser Tom Wopat was won over by the DeFroster 2000, a revolutionary new device that defrosts frozen foods in literally seconds. "It's impossible," a disbelieving Wopat said after hearing about the remarkable product, available through an exclusive television offer for $24.99. "Why, this steak is frozen solid." Moments later, Wopat broke out in astonished laughter as the DeFroster 2000 proved him wrong. Wopat added that he is available for work.
