You're always karkin' 'bout the money I spent,
You never quit screamin' 'bout payin' the rent.
[ Lyrics from: http://www.lyricsfreak.com/p/paul+mccartney/crackin+up_20105604.html ]
Quit buggin' me, yeah, yeah.
He's crackin' up, yeah, yeah.
He's crackin' up, yeah, yeah.
He's crackin' up, I'm crackin' up, baby.
