Rap covers of pop songs (or vice versa)

Anyone know any covers of songs, where they take a song with a melody, and turn it into a rap but use the same lyrics? Or the other way when someone turns a rap into a sung version?

Another thing that would be fun is a well-known poem set to rap.

As an example, here are some nursery rhymes performed as raps.

Walk this Way is pretty much the best known example of this category.

The Beach Boys and the Fat Boys collaborated on a version of Wipeout with rap lyrics.

There’s a bit of a joke that Rex Harrison supposedly invented rap. He couldn’t sing, so he just spoke all his lyrics in My Fair Lady and Doctor Doolitle etc.
