NO ONE'S EVER ENJOYED THE JOB MORE:

Gordon Brown thrown by George Bush's hip-hop handshake (Tom Chivers, 17/06/2008, Daily Telegraph)

Instead of going in for a straight grip-and-pump, with the fingers slipping under the wrist, Mr Bush gripped around Mr Brown's thumb, to the obvious confusion of his partner in the War on Terror.

The unusual, "street"-style greeting, more commonly used by young sports stars and musicians than middle-aged heads of state, so perplexed Mr Brown that three of his fingers somehow slipped inside Mr Bush's jacket sleeve. [...]

The handshake, which took place at RAF Aldergrove in Northern Ireland, was not Mr Bush's first high profile foray into youth-culture territory during his presidency.

The American Commander-in-Chief was famously caught on microphone, during a G8 meeting discussing Hezbollah attacks on Israel, asking Mr Brown's Prime Ministerial predecessor Tony Blair "Yo, Blair. How you doin'"?

Posterity does not, alas, record Mr Blair's response.
