BBC News website readers have been sending us their own humorous views about the credit crunch.
Following the problems in the sub-prime lending market in America and the run on Northern Rock in the UK, uncertainty has now hit Japan. In the last 7 days Origami Bank has folded, Sumo Bank has gone belly up and Bonsai Bank announced plans to cut some of its branches. Yesterday, it was announced that Karaoke Bank is up for sale and will likely go for a song while today shares in Kamikaze Bank were suspended after they nose-dived. While Samurai Bank are soldiering on following sharp cutbacks, Ninja Bank are reported to have taken a hit, but they remain in the black. Furthermore, 500 staff at Karate Bank got the chop and analysts report that there is something fishy going on at Sushi Bank where it is feared that staff may get a raw deal.

An elderly lady receives an e-mail from the son of a deceased (but wealthy) African general, asking whether he could transfer millions of pounds into her bank account in return for a 20% cut. All the son needs is the sort code and account number. Not realising she is the victim of a Nigerian 419 fraud, she e-mails back the details. A couple of minutes later she receives an e-mail back from the general's son: 'Icesave?!' What is this, some sort of scam?"

Resolving to surprise her husband, an investment banker's wife pops by his office. She finds him in an unorthodox position, with his secretary sitting in his lap. Without hesitation, he starts dictating, "...and in conclusion, gentlemen, credit crunch or no credit crunch, I cannot continue to operate this office with just one chair!"

If you had purchased $1000.00 of Nortel stock one year ago, it would now be worth $49.00. With Enron, you would have $16.50 left of the original $1000. With WorldCom, you would have less than $5.00 left. If you had purchased $1000.00 of Delta Air Lines stock you would have $49.00 left. If you had purchased United Airlines, you would have nothing left. But, if you had purchased $1000.00 worth of beer one year ago, drank all the beer, and then turned in the cans for recycling, you would have $214.00. Based on the above, the best current investment advice is to drink heavily and recycle. This is called the 401-Keg Plan.

Robert Fulford, London, UK
Three investment bankers are sitting outside a coffee shop, sipping glumly on their cappucinos. The first one says "It's terrible, I have lost five million on my accounts this morning, there is no way to recover my losses. When I get back inside I'm going to go past my office, up to the fifth floor, open a window and jump out" The second one says "You think that's bad; I've lost nine million on my accounts in the last hour, I have nothing left. I'm going to ride the lift all the way up to the ninth, open a window and jump out" The third one says "I'm glad our building only has fourteen floors."

Funnily enough, I run a creative thinking course which uses comedy to demonstrate how novel solutions can be found. When I approached the banks with the idea of running the course for their staff, they laughed. I bet they're not laughing now...(to paraphrase Bob Hope).
