Matthew McConaughey goes jogging with no undies

Matthew McConaughey was papped this weekend out jogging with no undies, proving that whatever Justin Timberlake can do, he can do better.

What is the deal with the male hollywood stars going commando. If we saw one of the female stars going braless and swinging in the breeze this way, the world would be morally indignant, praising the need for restraint and underwear in the appropriate size with the appropriate support.

Is it because its McConaughey and we all know he is a bit of a nut job or do we definitely have such different standards?
