Binucleate cells of transitional epithelium (bladder)?
In other stratified epithelium, it is the basal cells that replicate to replace the cells lost in the top layers.  In transitional epithelium, which is also a stratified epithelium, the most superficial layer of cells are replaced or  turnover occurs because of mitosis of the superficial facet cells themselves.  In this case it is not unusual to see dividing cells in its last stage of division as a large cell containing two nuclei, which soon that cell will be 2 cells.
