Since the Magna Carta was signed almost exactly 800 years ago many ludicrous laws have been passed.

Here are 12 which might well be the craziest of all, at least in the context of our 2015 standards of what’s reasonable.

Some of them have perhaps been loosely interpreted, but as far we know they are all genuine laws which could be enforced.

12 MOST LUDICROUS LAWS OF ALL TIME:

1. It is against the law to carry a plank along a pavement (1839).

This Is Local London: Marc Winter and Michael Bowles, of Reeman Dansie, with the Plank

2. Under this same law it is illegal for any person to fly a kite or slide on ice or snow whilst in the street (1839).

3. Any dead whale or sturgeon found on the British coast automatically becomes the property of the Monarch (1322).

4. It is illegal not to tell the tax man anything you do not want him to know, but legal not to tell him information you do not mind him knowing (2006).

5. It is illegal to enter the Houses of Parliament in a suit of armour (1313).

This Is Local London: Mark Harris, of the Britsh Plate Armour Society

6. It is an offence for a pub landlord to allow drunkenness in their pub - in other words it is illegal to be drunk in a pub! (1872).

7. In London, it is illegal for a person (knowingly) with the Plague to ride on a bus (1984).

8. It is illegal to keep a pigsty in front of your house - unless duly hidden (1847).

This Is Local London: These little piggies went to the Smallholder and Garden Festival. More than 200 pigs will be on view at the festival.

9. It is an offence to be intoxicated and in charge of a horse or cow (1872).

10. It is illegal to handle a salmon in suspicious circumstances (1986).

11. It is illegal to beat or shake any carpet or rug in any street. However, beating or shaking a doormat is allowed before 8am (1839).

12. No person shall import into England potatoes which he knows to be or has reasonable cause to suspect to be Polish potatoes (2004).

This Is Local London: Earth-up to produce good potatoes.

These loony laws, and others such as sticking a stamp on an envelope upside down, will be put to the test in a suitably wacky way at The London Dungeon in June.

The 800th anniversary of the Magna Carta will be celebrated with Judge Lord Wendy Farqhuar’s London Dungeon Court inviting visitors to ‘fess up to their crimes as part of a new courtroom show running for the month.

Fond of dispensing the death penalty, defendants are likely to find themselves on a short walk to Tyburn before being condemned to ‘take the drop’ on Drop Dead Drop Ride to Doom, a thrilling vertical freefall ride at the South Bank attraction.
