What are the most diabolical pizza toppings you’ve come across?

I don’t mean standard pizzas you can get from a takeaway like Hawaiian etc (we’re not here to debate pineapple on pizzas) but random things people put on them when doing pizza at home.

For example, my husband puts half a can of tuna and then half a can of baked beans over that, then tops it off with extra cheese. Tuna and beans 🤢
