This reminds me of a joke I received through email recently:

Proof that Men Have Better Friends...

Friendship among Women:
A woman didn't come home one night. The next morning she told
her husband that she had slept over at a friend's house. The man called
his wife's 10 best
Friends. None of them knew anything about it.

Friendship among Men:
A man didn't come home one night. The next morning he told his
wife that he had slept over at a friend's house. The woman called her
husband's 10 best friends. Eight confirmed that he had slept over, and
two said he was still there.
