Mixed Metaphors

I was listening to the radio the other day when this guy says, “You gotta realize it’s a 4-way street!” Really? What exactly is a 4-way street? The guy had mixed up a couple metaphors (4-way stop and 2-way street). That reminded me of a Mike Tyson quote I heard live in 2002 when Tyson said to Lewis, “I take my hand off to you.” So, for the last several weeks, I’ve been listening for and researching some commonly mixed-up metaphors. Here’s just a few:
“A car comes up behind you, flashing his horn.” – Aaron Colwick
“A heart as big as gold” – Kathy Scott
“A leopard can’t change his stripes.” – Al Gore
“A rolling stone is worth two in the bush.” – David Beck
“As we consider the road that unfolds before us.” – Barack Obama Jr.
“One has to tidy up the loose ends.” – Agatha Christie
“Button your seat belts.” – Rush Limbaugh
“Dirty laundry is coming home to roost.” – Ray Romano
“I was the mother hen to all these little ducks.” – Sandy on “Survivor”
“If you let that sort of thing go on, your bread and butter will be cut right out from under your feet.” – British foreign minister Ernet Bevin
“Just then, the fickle finger of fate reared its ugly head.” – Selby Anderson
“Life, liberty, and the pursuit of justice for all.” – Johnny Cochran
“Now, Senator McCain suggests that somehow, you know, I’m green behind the ears.” – Barack Obama Jr.
“They counted the votes until the cows had literally gone to sleep.” -Dan Rather

So, what metaphors do you commonly mix or have you heard mixed?
