Money is no joking matter, but that doesn't mean that investors can't have a sense of humor. Here are six jokes covering financial news that has broken over the past week. Apologies in advance if they fail to educate, amuse, or enrich.

1. Why did Ford (NYSE:F) delay the introduction of its F-150 pickup truck, in these gas-guzzler-weary times?

  • V for Vista, a rebel flick in which an unwanted operating system exacts revenge against those who denied it a shot at glory. XP marks the spot.

I have no idea, but I like the way you think.

4. Executive defections continue at Yahoo! (NASDAQ:YHOO). Which of the following bumper stickers was found on a car in the company's parking lot?

Nutflix.

6. China announced a 17% increase in gas prices on Thursday. What was the immediate reaction?
