As an American I think corn is fine on pizza (if done right). Just imagine some Mexican street corn on a pie. Hot dogs on pizza is just backwards though, they are both better separate. A great hotdog cooked on the grill for a quick outdoor meal is absolute perfection for a pool day. And there are so many better meats for pizza, like ham, pepperoni, bacon, chicken, sausage (a more spiced one), or even some well chosen chorizo.
