Crack in the ceiling
Expensive repair.

Crack in the glass    
Duct tape

Crack of a switch
Stripe the *****

Crack of a gun
Someone's done

Crack the vein
Relieve pain

Crack of lightning
Frightening

Crack the whip
Obey

Crack my skull
My mind mulls

Crack the mirror
Old wives’ tales dither

Crack the door
It's  her …

Crack of her ***
Beautiful tail
Ends this tight little piece
