Put all your eggs in one basket
Don't risk it all on one thing
Put your foot in your mouth
say or do something embarrassing or that offends somebody that you should not have
Pick your brain
hear your thoughts
Straight from the horse's mouth
getting information directly from the most reliable, firsthand source
Out of the blue
without warning; unexpected
I'm listening
Fish out of water
a person in a completely unsuitable environment or situation
Take it with a grain of salt
regard something as possibly exaggerated; believe only part of something
the ball is in your court
you make the decision
Beat around the bush
discuss a matter without coming to the point
Head in the clouds
be out of touch with reality; be daydreaming
pull someones leg
tease someone
Spill the beans
reveal secret information unintentionally or indiscreetly
Take a rain check
politely decline an offer, with the implication that one may take it up at a later date
come rain or shine
either way we are doing it
