Each of these items is actually a playing card and you are well on your way to memorising the order of a pack of cards.
Derren Brown's in his book 'Tricks of the Mind' describes a peg system where each number reminds him of a sound.
In his system
0 sounds a bit like z
1 looks like an L
2 is n as it has has two down strokes
3 is m as it has three downstrokes
4 is r because it sounds like fouR
5 is v because fiVe
6 looks like a b
7 looks like a T
8 has a gh/ch/j sound in it
9 looks like a g
Now when you need to remember a number the digits become sounds and those sounds become words. With cards the suit of the card becomes the start of the word. So hearts H, Clubs start with a C, Spades S and Diamonds are words starting with a D.
A hen is 2 of hearts
Cash is 8 of clubs
Hive is five of hearts
Adolf Hitler is Ace of Hearts each of the picture cards I represent with a person. Kings are people with the surname King.
Jack White is the Jack of hearts. Jacks are younger men. Queens are famous queens or actresses you have played the queen.
It is vital you make the memory as vivid as possible. Change the objects size so it looks ridiculous like a Tiny Jack White in a sink. Have the thing doing something that produces an emotional reaction like the bee stinging you. Rude things are really memorable so use them when you can.
I won't list out exactly what words go with what cards. It is better you pick words that mean something to you. The six of clubs could be Cob a Cub a Cube or a Cab pick whichever one is most vivid to you. When you have a word for each card buy a deck and write the word on each card. Then shuffle the deck and walk around the house putting each card down in a location. Talk out loud about what is happening. "The Dinosaur in the Shower is really scared of the water and is screeching as it tries to escape". Dinosaur is 2 of Diamonds for me. When every card has been placed start back at the first card and try and list what the next one is before you pick it up. Name the object do not worry about the card it represents yet, you will remember the connection in time.
People have great memories for locations. You can probably describe the route and details along it of a walk you took on holiday years ago but be unable to think of anything you discussed that day. Great memorisers use this ability in what is called the method of loci to put things to be remembered along a known walk. Everyone knows their house well so that is a good location to use to practice memorising a deck of cards. To memorise a poem or mathematical constant a walk near your house might be ideal.
This method of remembering things is ancient. The story goes that about 500BC Simonides of Ceos snuck out of a banquet for a sneaky smoke when the building collapsed crushing to death everyone inside. Making the best of a bad situation Simonides realised he could remember where everyone was sitting and point out the spot so the realtives could dig out their loved ones. This trick of using locations for memory was borne out of this unlucky event.
Building were always falling on the Greeks. Take the case of histories worst loser. Kleomedes of Astypalaia was an Olympic boxing champion in the early fifth century BC. In 496 he killed his opponent at Olympia with a foul blow. Because of this fouling offence (not because of the death of his opponent which was considered fine) the Olympics judges took away his victory.
Kleomedes became depressed. On his return to Astypalaia he destroyed a school by pulling down the pillar which kept up the roof in a flash of insanity and so killed all sixty children present. The inhabitants of the city formed a mob and tried to kill him.
He hid in the temple of Athena, from where he disappeared miraculously. His confused pursuers consulted the oracle of Delphi and were told that Kleomedes had become a hero. From then onwards he was honoured with sacrifices. Think about that one next time someone talks about how clever the ancient Greeks were or how mass killings are an entirely new phenonomen. Also this story does illustrate quite how much random stuff I am willing to put into a blogpost.
Memorising large amounts of data even random looking data is quite easy with a system to turn the data into something concrete. I recommend Derren Browns book on how to improve your memory and Joshua Foer's 'Moonwalking with Einstein' a few simple techniques and a few minutes practice everyday can have you performing feats most people find unbelievable.
What is on your bed? If you remembered a giant Hen you are well on your way to memorising a deck of cards.
