80,000 blondes meet up at the NEC for the national "Blondes Are Not Stupid" convention.

Their leader says, "We are all here today to prove to the entire world that blondes are not stupid. Can I have a volunteer?"

A blonde gingerly works her way through the crowd and steps up onto the stage. The leader asks her, "What is 15 plus 15?"

After 15 or 20 seconds she says, "Eighteen!"

Obviously everyone is a little disappointed, then 80,000 blondes start shouting, "Give her another chance! Give her another chance!"

The leader says, "Well since we've gone to the trouble of getting 80,000 of you in one place and we have the world's press and broadcasting media here, I suppose we can give her another chance." So he asks, "What is 5 plus 5?"

After nearly 30 seconds she eventually says, "Ninety?"

The leader is quite perplexed, looks down and just lets out a dejected sigh. Everyone is pretty disheartened. The blonde starts crying and the 80,000 other blondes begin to yell and wave their hands chanting, "Give her another chance! Give her another chance!"

Their leader, unsure whether or not he is doing more harm than good, eventually says, "Ok! Just one more chance. What is 2 plus 2?"

The girl closes her eyes, and thinks very deeply. It takes a whole minute before she eventually says, "Four?".

Throughout the whole building chaos breaks out as all 80,000 girls jump to their feet, wave their arms, stamp their feet and scream, "Give her another chance! Give her another chance!"
