Half your cake and eat it two

I dedicate this exercise in amalgamated idiomatic phrases to Becky, without whose influence this would have been more difficult, but under whose tutelage it was a piece of pie:

• A stitch in time saves the silver lining.
• You can burn that bridge when you get there.
• Shoot from the laurels and rest on your cuffs.
• I heard it straight from the gift horse's mouth.
• The grass is always greener before the dawn, and darkest on the other side.
• It's easier for a camel to go through the eye of a needle in a haystack than find the last straw that broke its back.
• Beer before liquor, sailors take warning. Liquor before beer, sailors delight.
• A bird in the hand is worth two in the frying pan.
• Have your cake and eat it like everyone else: one leg at a time.
• Hind sight is 50/50*

*Thanks for reminding me of this one, Julie! :D
