Blinded By the Light was a big one for me. I loved the sound, but for decades I was repelled by the song, because I had misunderstood the lyrics starting from 2:07 as:
"And Little Early-Birdy gave my a**s curly-wurly, and asked me if I needed a ride."
If you're unfamiliar with the song and listen to that part, you'll know the word it sounds like.
I also thought the part at the beginning at 0:14 was:
"Wrapped up like a douche, another roller in the night."
For years, I thought this song was some thinly-veiled code about some old perv cruising around in his car, and always wondered how they could play it on the radio. I sure am glad I discovered the actual lyrics. Even though they're nonsensical (IMO), at least they're not what I thought they were.
