What do you call an Elf that sings?

This joke is a pun that plays on two meanings of the word “wrapper.” In the context of elves, often associated with making and wrapping presents in Christmas lore, the term “wrapper” would naturally be thought of as someone who wraps gifts. However, the joke takes a twist by connecting “Elf” with “sings,” leading to the punchline “a wrapper,” which sounds identical to “a rapper,” a term for someone who performs rap music. The humor lies in the unexpected shift from the traditional image of an elf wrapping gifts to the amusing idea of an elf as a rap artist, blending the festive Christmas theme with a modern musical reference.
