What do you put on your pizza?

So I was eating dinner tonight when I realized that I have a habit of pouring either ranch dressing or hot sauce on my pizza. It alternates with each slice.

My dad covers his with pepper and my mom is weird and eats it plain. One of my cousins puts barbecue sauce on his, while his brother swears that a little bit of honey is magical on pizza.

Do you put anything different on your pizza?
How did that start?
Do you know anyone who puts different maybe weird? things on their pizza?
