We know that laughter is infectious – there’s that old saying that laugh and the world laughs with you, cry and you cry alone.

Coca-Cola proved the point about the power of laughter with this cute and disarming ad:

It’s pretty self-explanatory — I admit that I laughed along with the rest of the people on the subway.

I could get scientific and academic about this – that the ad is a good example of Game Theory and positive tit-for-tat dynamics in action.

But the bottom line is that the ad demonstrates that in life and in business – have fun! Otherwise what’s the point?
