The Arsenal legend thought he was catching a quiet lift when he hopped into a London cab.
But it was all a big prank from bookies 888sport.com.
The driver, wearing the keeper’s old England shirt, claims to be a Seaman mega-fan.
He’s at the wheel of the cab in keeper gloves and even says he’s bought Seaman’s old ponytail.
Except it turns out to be a lie, with the England legend revealing it’s in his drawer after being cut off!
