It has been noted that one of the problems with Islam is a well-defined lack of humor. Over at a blog entitled Planck’s Constant, an effort is underway to make up for that deficiency. Some samples:

What do you say to a Muslim woman with two black eyes? What’s to say? You already told her twice!

What do you call a first-time offender in Saudi Arabia?
Lefty!

What does the sign say above the nursery in a Palestinian maternity ward?
"Live ammunition."

A man goes into an adult entertainment shop and asks the assistant for an inflatable doll.
"Would you like male or female?"
"Female, please."
"Would you like Black or White?"
"White, please."
"Would you like Christian or Muslim?" This question confused the man, so he asked, "What has the religion got to do with it? It's an inflatable doll!"
"Well," explained the assistant, "The Muslim one blows itself up!"

Hassan, a Palestinian, sees a friend over the Israeli fence. "Hey, Achmed, how do you get on the other side?" Achmed looks at him, scratches his head and says, "Hassan, you are on the other side."

And, of course, the obligatory light bulb joke,

Q. How many Palestinians does it take to change a light bulb?
A. None! They sit in the dark forever and blame the Jews for it!

Rob adds: These would be funny if they were so true.
