Clothes do not make the man.
Cleanliness is next to Godliness.
Cowards die many times before their deaths.
Curiosity killed the cat.
Cross the stream where it is shallowest.
Don’t bite off more than you can chew.
Don’t bite the hand that feeds you.
Don’t cast pearls before swine.
Discretion is the better part of valor.
Curses, like chickens, come home to roost.
