They're coming to take me away
 

In the song, the story is told in the first-person by an insane dog owner who is raving he will be taken away to a mental institution, referring to it as the "funny farm" and "happy home". His dog has run away and he is having an imaginary discussion with it ("Well you just wait, they'll find you yet, and when they do they'll put you in the ASPCA, you mangy mutt"). The cover art shows a spoof "Napoleon" holding an invisible dog on a leash, the collar being next to a fire hydrant (presumably so the dog can relieve itself).

I am now informed. We were forced to sing that in 7th grade music class.

That's kind of funny, since when it was released it was banned from a few stations because of the fact that it appears to make fun of mentally ill people.

I'm honestly finding it weird you happen to know so much about this song.... Did you sing it?

I read the wikipedia page. My first post was directly from the wiki.

They're Coming to Take Me Away, Ha-Haaa! has the distinction of being the song to drop the furthest within the Top 40 in a single week. It charted for 5 weeks during 1966; in week 3 it peaked at #3, scored #5 in week 4, and fell to #37 in week 5. This was due to radio programmers removing the song from their playlists, fearing an adverse reaction from people who might consider the song as ridiculing the mentally ill. This occurred most notably in the New York market, where both the New York Top 40 music radio stations of the time, WABC and WMCA, banned broadcasting of the song. (WABC continued to include the song on its local Top 20 list despite no longer broadcasting it.)[2]

Opposition to the banning saw teenagers picketing WMCA, carrying such signs as: "We're coming to take WMCA away! Unfair to Napoleon in every way." In contrast, a plane flying a banner protested WMCA's banning the record.

About 10 seconds after I posted that and went to school, I realized what you must have done.

I can't believe they make such a big deal about things like this, but play Boondock Saints on T.V. every week.
