Sweet and salty go great together, as do fruit and pork. I'm convinced half the people who say they don't like pineapple on pizza have just never tried it.

I remember thinking it would be gross as a kid but then tried a slice when a friend's family ordered one and really enjoying it. Told my dad I wanted it next time we ordered pizza and he refused and made me buy my own because "nobody wants that garbage and it'll get thrown away". Ate some that night then went to bed, went to eat the next day and he'd eaten every leftover slice overnight. From that day on, he only ordered Hawaiian and I got completely burnt out for years.
