A little hand quiz

[Penguinfan]

After all 5 cards community cards have ben exposed and you go to the showdown what is the worst poker hand you can have and it still be the absolute nuts?

Not simply your starting hand as I realize 2-3 could be the nuts on a board of 2-2-2-5-9, but your lowest final hand that could be the nuts.

Hope that is clear as I am pretty sure I have the answer but might not. Tell me what your answer is and what the board would have to be for it to be the case.
