    Write a short Python function that takes a sequence of integer values and
    determines if there is a distinct pair of numbers in the sequence whose
    product is odd.

    --------------------------------------------------------------------------
    Solution:
    --------------------------------------------------------------------------
    The product of two odd numbers will produce an odd number.  If there are at
    least two (unique) odd numbers in the sequence, the function should return
    True.
