I am trying to remember an idiom I have heard before but can't remember. It goes something like:
They couldn't figure out how to [insert thing here] if they flipped it over to read the instructions.
I'm pretty sure thing is something that simply requires being turned upside down to be accomplished, but google hasn't been much help.
Does anyone know the idiom I'm thinking of?

A slightly bowdlerized version of what I believe you’re thinking of is “He couldn’t pour water out of a boot with the directions printed on the bottom of the heel.” There’s more discussion about it here.
