Rottweiler

Why are many musicians not known for enunciating their lyrics? Share your misheard lyrics here.

Classic: Led Zeppelin, Stairway to Heaven
"And as we wind on down the road / Our shadows larger than our souls" becomes
"And there's a wino down the road / I should've stole his Oreos"

Recent: Lady Gaga, Alejandro
"She's got both hands in her pocket" becomes
"She's got both hens in her bucket"

GLORIOUSLeader

And, of course, the all-time reigning champion:

"'Scuse me, while I kiss this guy/the sky" - Jimi Hendrix, Purple Rain 

Rottweiler

Pearl Jam, Glorified G:
"Glorified version of a pellet gun" sounds like
"Glorified virgin on a pelican"

RocketDude

"Blinded by the Light,
Revved up like a douche,
Another roller in the night."

From Blinded By The Light by Manfred Mann's Earth Band.

Stormtroper

Not lyrics, but from the Half Life: Full Life Consequences machinima:

"John Freeman who was Gordon Freemans brother was one day in an office" -> "John Freeman who was Gordon Freemans brother was one day an office"

"he blew up the house and killed the zombie goasts so they were at piece." -> "he blew up the house and killed the zombie goasts so they were happy."

I was disappointed when I found out the actual lines.

Can't think of any right now, but "mondegreen" has the best etymology of any word I've heard.
