Is this the beginning of a trend?
Scarlett Johansson did the weather on the Today show in November. She stepped in when Al Roker was suffering from laryngitis to give voice to the highs and lows of the day.
Today, Mark Wahlberg, in town for a screening of his movie Broken City, helped out on WTXF's Fox show, Good Day Philadelphia, taking it all very seriously, until he totally cracked up during the traffic report.
"Warmer temperatures are still hanging in there," he told the viewers. Then he ad libbed the entire traffic report, making up stories as he went along. "Expect delays here ... stop and get yourself a hoagie."
