Yes.
The oddest pizza I ever had (but very, very good!) was a Maryland Seafood pizza at a little brick-oven pizza place/microbrewery in western Maryland (sadly, they went out of business. . .). Thin, crispy, brick-oven crust; covered (in place of marinara, which probably would have overpowered the seafood) with something like a thinned-out crab dip (combo of crab meat, cream cheese and spices), topped with tiny shrimp, an Italian 6-cheese blend, and topped finally with fresh diced tomatoes after it came out of the oven! Mmmmmmm.
As a bonus, you could order, for $5.00, their “beer sampler”: 6 4oz glasses of whatever their featured micro-brews were that day!
Hubby and I would go there on “Two-fer Tuesday”, when it was buy one pizza, get one free.
I had a Haggis pizza for dinner last night. It was very nice indeed.
Oh… odd. Is it actually a license of the original comics/toys, or is it a borrowed name or odd coincidence?
Fried egg is actually a very traditional pizza topping. You’re supposed to crack it on the pizza raw and ‘fry’ it in the pizza oven with the pizza. I can’t get it to cook fast enough in my home oven. 
The oddest pizza I’ve had was in Buenos Aires: a white pizza (cheese but no tomago sauce) topped with hearts-of-palm. It was pretty good.
Argentina had a lot of immigration from Italy, and has an amazing range of pizzas.
You can get that too in some places in Germany, usually in combination with spinach and garlic. It’s not bad.
Ah yes, Shakeys! I remember going there to indulge in “pizza”. In our local one there’d be lots of the squid and nori variety left over, and the meaty ones or the tomatoey ones would be snatched out of the server’s hands before they could put them out on the lunch bar!
I saw one advertised the other day with kimchee on it. Bleh.
Its even better when its Lutefisk Haggis 
In 1982 when I first moved to Korea a new pizza place had opened up in Hannam Village. I was there on opening night and the pizza was awful, my kids would not eat it. So I did the neighborly thing and went back to the kitchen and spoke to the manager. I spent the next hour teaching them how to make a pizza. Ate there once a week for two years, always got free pizza.
You just blew my mind. Might be gilding the lily a bit though…
Dave Barry mentioned the ubiquity of corn in Japanese food, most surprisingly in pizza. I have to admit that I’d find it weird (not to mention the presence of mayonnaise)
Here in the US, one store sold “Chinese Food Pizza”, which had different types of Chinese Food simply placed atop your generic red-sauce-and-mozzarella pizza. Pepper Mill says that she and her friends were doing that kind of thing long ago.
Speaking of which, at one of our Bad Film Festivals we had a “make your own pizza Bar” for refreshments, and pepper Mill made a dessert pizza of sliced apples and some sort of white sauce atop a traditional crust. Pizza really ought to be a mucxh more free-form food than the Marinara Sauce and Mozzarella Cheese that we have pigeonholed it as.
Worst, I’ve had is in Germany, where canned tuna on pizza is very popular. Bleccchhh!
I’ve added surimi (artificially-crab-flavored processed whitefish) chunks to various pizzas at home, along with extra sauce or fried tomato slices. Yum!
A small chain in NH called Foodies had (has?) a Reuben Pizza, with all of the normal Reuben ingredients (corned beef, kraut, thousand island dressing, swiss cheese). It’s actually quite good.
I had some abominations called pizza in Nepal, where they basically call anything served on flat bread “pizza”.
To be fair, I stole that horrible concept from someone else in the Lutefisk thread.
If it was missing the egg, then definitely bleccchh! With the egg, OTOH, that’s good eats 
Actually, the only time I went to Europe, I mistakenly ordered something similar thinking it was chicken.
I got two slices of Tuna Pizza, and actually it was quite Divine. I’ve always wanted to go back and try to get some more of it.
It was I believe in Vatican City that I got the pizza- if there’s one thing those Vaticans know how to do… it’s Cafeteria style delicious Tuna Pizza.
I was hoping this thread was going to be about okonomiyaki, which is sometimes described as “Japanese pizza” despite not really resembling pizza very much.
When I lived in Japan I only ate pizza in Italian restaurants, but I would get flyers in my mailbox for local delivery places that offered some (to my mind) pretty weird selections. Like tuna, squid, or cut up pieces of hard-boiled egg. That last one came with mayonnaise too, for those who really love egg products I guess. Oh yeah, and there was one that had a RAW egg cracked in the middle. Compared to that, the popularity of corn as a pizza topping in Japan seemed pretty mundane.

“Potato Gold” potato wedges, bacon, corn kernels, ground beef, a drizzle of sour cream, a crust stuffed with sweet potato puree. It was “good”.
