Easy(?)
1
Close but no cigar
3
That’s my cross to bear
7
Everything from soup to nuts
2
Tongue in cheek
5
Straw that broke the camels back
8
Doesn’t know me from Adam
4
Spill the beans
6
When pigs fly
9
The pot calling the kettle black
11
Snowballs chance in hell
10
Don’t look a gift horse in the mouth
12
Close only counts in hand grenades and horseshoes
