Ananova: Beckhams replaced by performing seals

David and Victoria Beckham were replaced by performing seals when they stood up one of the biggest names on American TV. They gave up a joint interview on the Jay Leno show, preferring to stay on holiday in Marrakesh, reports the Evening Standard.
Network chiefs hastily issued a new schedule, replacing the couple with a display of performing animals from the SeaWorld theme park.

Probably a good choice for replacements, I doubt whether anyone noticed except I'll bet Jay Leno got more understandable and abstract conversations from the Seals than he would have from the Beckhams.
