An apple a day keeps the doctor away.
A bird in the hand is worth two in the bush.
A rose by any other name would smell as sweet
The more things change, the more they stay the same,
The grass is always greener on the other side.
There is more than one way to skin a cat.
You have to kiss a few frogs before you find a prince.
A penny saved is a penny earned.
It's not the heat, it's the humidity.
Beware of Greeks bearing gifts.
