You know you're in trouble in politics when the Liberal Democrats start laughing at you.
The Lib Dems have provided much amusement for the main UK parties over the years, particularly during leadership elections.
Today, the tables turned and it was Gordon Brown's turn to become the butt of a Lib Dem joke.
Today, the party's acting leader, delivered the best line during Prime Minister's Question Time: "The House has noticed the Prime Minister's remarkable transformation in the last few weeks from Stalin to Mr Bean."
Vince Cable may look like Ming Campbell's older brother but he's generally seen to have played a blinder as acting leader, highlighting Northern Rock before others spotted the problems.
He'll be gone in two weeks, replaced by Nick Clegg or Chris Huhne. Mr Cable's a keen ballroom dancing fan - I wonder if he's done enough these last few weeks to get a slot on the next Strictly Come Dancing?
