Never could get myself to give that a fair chance. Love Pineapple, like Ham, love Pizza, but all 3 together just don't sound appealing.
I remember the first time I had a Hawaiian pizza, over my sister's house and she suggested getting that and i thought the same thing as you, thought it was a weird thing to put on pizza. Well, I loved it. I now prefer it with bacon and pineapple and mushrooms but if I can't get it with bacon I'll gladly eat it with the ham. You should give it a try because it's a great combo!
