Got Milk?

A man walks into a T-Shirt store and on the walls there where three t-shirts on display for sale.

The first row had the picture of Richard Nixon with a thin white mustache and below the picture it was titled: GOT MILK

The second row of shirts were the picture of Ronald Reagan with the white mustache and it was titled: FORGOT MILK

And the third was of Monica Lewinsky with a white mustache and under her it was titled: NOT MILK
