Yeah, pineapple on pizza is apparently one that tends to get people going whenever I mention it. :'D Personally, while it's not my favorite, it's still a combo I like to enjoy from time to time.
People also looked at me funny when I said I was eating chocolate-covered potato chips.
And then there was the one time I made bacon chocolate chip cookies. Oh the responses were polarizing. Half of them were "that sounds amazing!" - of which my brother was one of those, and then suggested chocolate chip cookies with cayenne pepper on them...have yet to try that though. The other half were, of course: "oh my god that sounds so gross how could you eat that!"
I would so eat those cookies again though, omg.
Oh yeah, and syrup is the one true condiment for breakfast sausages of any kind, no questions asked.
