Right, first up is Big Ben, the big clock with the pointy turret that's stuck on the side of "The Houses of Parliament". As clocks go, it's possibly the most recognised one in the world. It's just over 315 feet high, was designed by Charles Barry and is, in fact, the world's largest four-faced, chiming clock. However, it's real name isn't Big Ben, it's "The Clock Tower", Big Ben is actually the name of the bell that chimes the hour.

Most Convincing Blag:

At the base of each clock face in gilt letters is the Latin inscription: "DOMINE SALVAM FAC REGINAM NOSTRAM VICTORIAM PRIMAM", which means "O Lord, keep safe our Queen Victoria the First".

Tower of London:

It was really crowded when you went to the Tower, wasn't it? All those tourists; no wonder it's always in the top 5 of London's attractions. O.K. so you saw the Crown Jewels, a couple of ravens and a Beefeater or two (they're the ceremonial guardians of the Tower). You thought Traitor's Gate, where Anne Boleyn entered the Tower, was pretty cool and Bloody Tower where the two young nephews of Richard the Third supposedly "disappeared" felt spooky.

Most Convincing Blag:

From the top of the White Tower (William the Conqueror's idea) you can see the River Thames, Tower Bridge and HMS Belfast.

British Museum:

What a cool place and it's free to get in! Established back in 1753, the British Museum's got more than 13 million objects and some countries would like them back. (Don't mention "The Elgin Marbles). You name it and this place has got it. Mummies, the Rosetta Stone, Viking treasure and that"s only for starters. You spent ages wandering round the Department of Greek and Roman Antiquities, amazing or what?

Most Convincing Blag:

At the centre of the Museum, the Queen Elizabeth II Great Court is the largest covered square in Europe.

Tower Bridge

Wow! What a view you had up and down the river from the covered walkways along the top of the bridge. Yeah, this is the bridge that opens in the middle when something big is travelling up the Thames. Sometimes, it's called London Bridge but that is, in fact, the next bridge upstream. Remember you had to buy tickets to get to the walkways and the Victorian Engine Room but it was worth the wait.

Most Convincing Blag:

Back in 1952, a crowded London double-decker bus had to jump over the gap in the middle of the bridge when the bridge started to open unexpectedly.

Gherkin:

Opened back in April 2004, the "Gherkin" as it's unofficially called, is 590 feet high and instantly recognisable. Winner of all sorts of awards like the RIBA Sterling Prize, it's enviromentally friendly due to its energy saving heating system. Whatever you do though, don't blag about the view from the restaurant and bar - it's not open to the public apart from Corporate events and Weddings.

Most Convincing Blag:

Depending on when you were supposedly in London you could have seen the filming of:

• Doctor Who, The Christmas Invasion
• Woody Allen's "Match Point"
• Basic Instinct 2: Risk Addiction

All of which have used the "Gherkin" as a film set.

Underground:

You can't really have travelled around London without using the Tube, so if you remember the names of the different lines your blag will sound more convincing:

Bakerloo, Central, Circle, District, East London, Hammersmith & City, Jubilee, Metropolitan, Northern, Picadilly, Victoria, Waterloo & City.

The nearest Tube stops for the above attractions are:

• Big Ben: Westminster or Embankment
• Tower of London: Tower Hill
• British Museum: Holborn,Tottenham Court Road, Russell Square
• Tower Bridge: Tower Hill
• Gherkin: Aldgate

OK, so you went to London, had a great time, also saw Nelson's Column (Tall statue in Trafalgar Square), Millenium Eye (Gigantic Ferris Wheel) and Buckingham Palace (Where the Queen lives - she wasn't in!).

Remember though, don't get carried away, because as the famous quote says "Oh what a tangled web we weave, when first we practice to deceive!" And no, after that we don't become a little bit better at it.
