Mondegreen! I didn't know there was a word for that!

I guess it is a kind of border-line mondegreen.

But here's one. The Jimi Hendrix song Purple Haze has the line "excuse me while I kiss the sky" not uncommonly misheard as "excuse me while I kiss this guy".

It's the idea that anyone could think Jimi Hendrix was somekind of psychedelic homoeroticist that cracks me up.
