There is a huge difference between guy's friends and women's friends.

Women:

A woman doesn't come home one night and the next morning she tells her husband she slept at a friends house.

Her husband calls 10 of her best friends.

None of them knew anything.


Men:

A man doesn't come home one night and the next morning he tells his wife he slept at a friends house.

His wife calls 10 of his best friends.

All 10 said he had slept over while 2 said he was still there.
