In a large bowl, mix together the corn, bell pepper, green onions, and cheddar cheese.
In a smaller bowl, whisk the mayo, sour cream, lime juice, smoked paprika, salt, and pepper.
Pour the dressing over the corn mixture and stir to coat everything evenly.
Cover and refrigerate for at least 30 minutes so the flavors can hang out and get friendly.
Give it one last stir before serving, and top with fresh cilantro if you like that sort of thing.
