Has anything embarrassing ever happened to Gordon Brown whilst campaigning?

I only ask because the BBC following up the story about the youth wiping snot on David Cameron's back are running a piece entitled " Campaign trail classics". This has nine examples - three about David Cameron, two about John Prescott, two about Tony Blair and two about Charles Kennedy. The BBC probably think that this covers them against any claims of bias - four Labour, three Conservative and two Lib Dem. Very clever, but of course the only person who is still a party leader or deputy is the Conservative.

The BBC never too proud to try and cast aspersions on Conservatives.
