I'm surprised none of the older posters mentioned "If You Want To Be Happy" by Jimmy Soul. The song extolls the positives of marrying a woman who isn't exactly "fair of face". The line "she'll always give you a piece of a$$" always cracked me up but, as I learned later in life, the guy's philosophy about pretty women was right on for the most part...
As long as Canada has been mentioned, I have 2 items. First of all, IIRC the "Rodeo Song" was played unedited in parts of the prarie provinces. Also, I always wondered what standards were in place up there. In the early 90's during a sensational murder trial in Ontario, the judge ordered a media ban on trial coverage but nobody raised an eyebrow when the morning guys on CFNY referred to one of the royal family as a "dic*head"...
The reason why no one has mentioned it is because the actual lyrics are "she'll always give you peace of mind.
Now, 'scuse me while I kiss this guy!
I know there's entire sites deticated to these, but I remember Stevie Nicks "Stand Back" where I used to think she was saying "Like a wierdo I can bend" (actually was Like a willow
I can bend"
...Same with "Love Will Find a Way" by "Yes" -it sounded like they were saying "I eat and shave you"
(really saying "I eat at chez nous"...huh???
