So there is an international confrence to find out what the head of a mans penis is for...

(please imagine appropriate accents)

The french delegate stands up & says, " We've spent 5 million dollars & found it's for the mans pleasure durring felatio"

The American delegate stands & says, "Well we've spent 5 Billion dollars & found its for the womans pleasure durring sex"

So the Australian delegate stands up & says, "Ah, we spent $50 & found out it's to stop ya hand flying off the end!"
