A piece of cake- Something very easy Under the weather- Not feeling very well Kill two birds with one stone- Complete two things with one action Pull someone's leg- Tease someone/joke with someone Hope this helps :)

"like a wet week"- seem very slow (if I say "that lecture went by like a wet week", I mean "that lecture seemed to go very slowly") "sleep like a log"- to sleep very well and deeply, without interruptions (especially after having a tiring day) "eat like a pig"- I think this one is pretty obvious, but it means to be very greedy or eat very quickly without thinking. "a no-brainer"- a decision that's so easy to make (taking an umbrella out with you if it's raining is "a no-brainer". "to go pair shaped"- (literally; "become the shape of a pear") for things to go all wrong! "don't count your chickens before they hatch"- (referring to having lots of eggs, and thinking that they will all hatch into chickens, when they may actually be crocodiles). Don't have high expectations, expect the unexpected. "put all your eggs in one basket"- to put all your faith/money/time into one thing/cause. That's about all I can think of for now, if you have any other questions, I'd be happy to answer them for you! :)
