I've got a memory
like a sieve
He eats
like a pig
I avoid her
like the plague
They are as dumb
as rocks
It's as dead
as a dodo
I felt
like a fish out of water
That's as clear
as mud
She's as cold
as ice
He is as deaf
as a doorpost
He drinks
like a fish
She's as hard
as nails
They're like
chalk and cheese
