hit the hay
when pigs fly
just around the corner
brake a leg
give a hand
gets itchy feet
take five
puppy love
call it a day
Snowed under
Hang in there
takes your breath away
carries the torch
working around the clock
Jump the gun
a whale of time
in a flash
miss the boat
stay in touch
once in a blue moon
piece of cake
On the ball
at the drop of a hat
stumbling blocks
