Subject: What type of cell in the human body has NO nucleus? MORE than 1 nuclei?

Hello!
I am participating in a weekly "science question" competition. I am to 
research questions, ask people, etc., to find the answer. It is not 
against the "code" to ask other scientists for help!
In this case, I have been provided with enough information to know that 
there are certain unique human cells which possess no nucleus, and those 
with multiple nuclei. I need to know which cells those are to complete my 
research.
Thanks so much!
