Here are two I enjoyed: Hopi Sen’s “What would Bertie Wooster do?” and The Daily Mash’s “Government takes 60% stake in Al-Qaeda”:

The prime minister said : “We must ensure that, as an institution, it continues to provide a useful, ongoing threat without actually blowing things up.”

The Daily Mash is a free online site. The Guardian is a national daily newspaper that sells for 80p a copy and uses some of this money to employ an “award-winning” cartoonist to draw George Bush as a monkey.

UPDATE: This is interesting too.
