There is a line in Paul Simon's Graceland which has always sounded to me like

"The way she brushed her hair and farted"

the actual verse actually being:

"She comes back to tell me she's gone
As if I didn't know that
As if I didn't know my own bed
As if I'd never noticed
The way she brushed her hair from her forehead"

On paper it's nothing like it but on the record...

At the risk of thread creeping there is a line in "The Town I Loved So Well" which I find hard to sing with a straight face -

"There was music there in the derriere"...
