Danny (Earworm)

From Tardis Wiki, the free Doctor Who reference

Danny was a young lad who became a host one night when a Harmonelid became buried in his ear. Fortunately the Eleventh Doctor had detected the worms presence and managed to somehow lure Danny and his dad to a nearby hospital in Leeds. An investigation into Danny’s ear with the sonic screwdriver caused the Harmonelid to flee and where the Harmonelid could have caused damage to such a young ear as Danny’s the Harmonelid was left to rest in another patient at the hospital a now deaf former musician – Mr Richards.
