Namath, who wore a white fur coat similar to the one he was seen wearing on the sidelines in 1971, joined Super Bowl XXI MVP Phil Simms in representing the host teams Sunday night at MetLife Stadium in East Rutherford, N.J.
Namath flipped the coin before the Seahawks' captains could make a call, leading referee Terry McAulay to catch the coin and hand it back to a laughing Namath for a second try.
The Seahawks won the toss and went on to become Super Bowl champions.
Namath's coat was such a big hit online that it inspired its own parody Twitter account, @joenamathscoat, the New York Daily News reported Monday.
