be well-oiled

have had a drop too much

have had one too many

have a hard-on

to have bats in the belfry

be tipsy

on fire

leap

to have bats in the belfry

have no idea

having no idea

not having a clue

have the guts

have an affair

hullabaloo

come at a price

don't stand a chance

I don’t feel like it

object

have a screw loose

hobnob

suspect

have a nice day
