Doughnuts?

I found myself singing tonight. It was an odd little song:

Doughnuts, doughnuts, all the lovely doughnuts;
Eat them now, eat them now!
Doughnuts, doughnuts, all the lovely doughnuts;
Eat them now, eat them now!

Then I realized this was set to some half-remembered Sunday School song. I also remembered some of those words were not quite the same. Oops.
