Subject: Comparing Arrays

I have two arrays: originalList and deleteList. I'm trying to iterate 
through original list and remove each item if it appears in the 
deleteList. Simple enough. Here's my snippet for doing this:

originalList.each do |item|
	if deleteList.include?(item)
		puts "Deleting " + item
		originalList.delete(item)
	end
end

Unfortunately, this code doesn't seem to be doing what I think it 
should. It seems to skip some items in originalList. I can provide 
examples upon request. Is there anything wrong with my algorithm?
