This advertisement for the Durex condoms is very simple, yet very clever at the same time.

The advertisement reads:
"To all those who use our competitors' products:
Happy Father's Day."

This advertisement sets the Durex condom apart from its competitors. It basically is saying that those who use Durex do not have to worry about pregnancy while the users of other condoms end up becoming fathers. I think this is a funny and smart ad.
