• be just a pretty face
• be just the job
• be just up someone's street
• be just up street
• be just what the doctor ordered
• be knee-deep in
• be knee-deep in something
• be knee-high to a grasshopper
• be larger than life
• be laughing all the way to the bank
• be laughing on the other side of face
• be laughing on the other side of your face
• be laughing up sleeve
• be laughing up your sleeve
• be left hanging
• be left hanging in midair
• be left hanging in the air
• be left holding the baby
• be left on the sidelines
• be level pegging
• believe a word of it
• believe it or not
• believe me
• be light-headed
• be light years away
