So... It's been said for as long as time has existed: Blonds have more fun.
However, based on the current stockpile of images in the "Smiles 'N Happiness" folder it can be actually concluded that burnettes are the ones having the most fun.
Burnette - 93 (36%)
Blond - 48 (19%)
Raven - 46 (18%)
Redhead - 41 (16%)
Other - 16 (6%) (these were images that the color couldn't be determined)
Blue/Purple/Green - 8 (3%)
(there is 2% missing because i rounded numbers.)
Conclusion: If you want to have more fun, be burnette. Now obvious arguement will be there are more burnettes, so ipso-facto there will be more smiles from them. This is true... but let's face it; this isn't a conclusive and true study of happiness. This is me just being bored one day and wanting to calculate numbers from one of our folders. If you do want to post on facebook that you have suffecient new evidence that burnettes are indeed having more fun. feel free to quote this article for your personal enjoyment of watching others sufffer under the hard cool facts presented here. Because nothing is better than Internet Facts.
also your enjoyment; some featured smiles:
