I guess coming from the Louie, Louie generation, we were wired to mishear lyrics.
...not to mention backtracking & backmasking.
Louie Louie - Wikipedia, the free encyclopedia
In February, 1964, an outraged parent wrote to Robert Kennedy, then the Attorney General of the United States, alleging that the lyrics of "Louie Louie" were obscene. The Federal Bureau of Investigation investigated the complaint. In June 1965, the FBI laboratory obtained a copy of the Kingsmen recording and, after two years of investigation, concluded that the recording could not be interpreted, that it was "unintelligible at any speed,"[27] and therefore the Bureau could not find that the recording was obscene.
