Wake up and smell the bullshit

Politicians have started to head for the comforting heights of cliché for the upcoming general election. The latest phrase is “wake up and smell the carbon” nothing worse then diamonds stinking out the gaff, pencil leads malodorous stench ruining the area.

Where did the expression "wake up and smell the coffee" come from? Presumably it is from teasmades which became yuppie cool in the 80’s. No one uses these anymore so why not update the expression to how we currently live?
"Wake up and have that half hard morning piss of truth"
"Wake up and remove that weird crumby stuff of hypocrisy from your eye"
"wake up and engage in some sort of existential Faustian contract with the snooze function"
Have you got any others?
