I had a buddy that thought "Witchy Woman" was "Pinche Woman." He was from South Texas so we gave him a pass.
For years, I thought it was "400 Children in a crop in the field." Not sure when I figured that out but it seems to be very commonly misheard.
A friend of mine thought it was, "Dirty Deeds and the Dungeon's free."
This same person mishears quite a few song lyrics.
My now 14 year old daughter thought Billy Joel was singing about a "tonic engine", not a "tonic and gin."
