Entrenched Ditty Derangement

The New Yorker describes my current affliction:

INFLUENZA 529, or Entrenched Ditty Derangement. The infected person displays an inability (in the worst cases, lasting months) to rid his cortex of an unusually repugnant melody. (In some extreme cases, lyrics are part of the malady.)

Symptoms: Early signs include innocuous humming in the workplace. In later stages, the sufferer may believe that he hears voices in his head. A large body of clinical literature exists on the topic (see “ ‘Horse with No Name’ Phenomenon”; “Complications Arising from the Theme to ‘Walker, Texas Ranger’ ”). In one famous case in New Jersey (known in medical circles as Embedded “Jessie’s Girl” Phenomenon), manslaughter resulted.

In my case, this is the culprit. This song has been in my mind for what seems like years (in reality, more like months):

For Jonathan it's:

He was able to exorcise that last night, though, I believe, by watching the video and laughing at the ridiculous intercutting of scenes between fighter planes and a sweaty Kenny Loggins lounging around in a hotel room lip-syncing.
