Some presidents get carved into Mt Rushmore; others have airports, motorways, and even entire cities named in their honour. But when George Bush leaves office, his most visible memorial may be a mouldering patch of human effluent.
In November, alongside casting their ballot for the next president, the people of San Francisco will also vote on a measure to rename one of the city's largest sewage works the George W Bush Sewage Plant, to provide a "fitting monument" to the outgoing commander-in-chief's achievements.
Activists from the Presidential Memorial Commission of San Francisco, a mischievously-named group behind the move, will ask supporters to participate in a "synchroni(z)ed flush".
It may sound like a student prank, but the proposal is almost certain to be passed. Democrats usually secure between 70 and 80 per cent of the vote in San Francisco - and in 2006 passed a proposition to impeach Mr Bush and his Vice-President Dick Cheney by a majority of almost two to one.
"In 50 years from now, we want people to see George Bush's name on that plant, and ask each other what went wrong," said Brian McConnell, the Memorial Commission's organi(z)er. "We want them to be reminded of the Iraq war, and his other dramatic mistakes, and this is the perfect way to do it."
