Back-of-the-envelope calculation
Bad workers always blame their tools
Beat the daylights out of someone
Beauty is in the eye of the beholder
Been around the block a few times
Before you can say Jack Robinson
Better be the head of a dog than the tail of a lion
Better than a kick in the teeth
Better than a stick in the eye
Between a rock and a hard place
Between the devil and the deep blue sea
Between you and me and the cat’s whiskers
Bird in the hand is worth two in the bush
Birds of a feather flock together
Bite off more than you can chew
Born on the wrong side of the blanket
Born with a silver spoon in your mouth
Broke as a joke and it ain’t funny
Busy as a one-armed paper hanger
Butter wouldn’t melt in their mouth
