That's just crazy talk (idea) by mblase

A useful all-around phrase when the person you're talking to just doesn't make sense. Or else needs to be shut up with a more polite phrase than "mind your own business".

Some sample uses might be:

"Hey, you're travelling about thirty miles over the speed limit." "Ah, that's just crazy talk, mom. The cops never monitor the alleys."
"Don't you think we should head back to the dorm? We have to take a Fourier analysis final tomorrow morning." "Nah, that's just crazy talk. Besides, Miss Moxie said she'd go home with me after her last dance at 3."
"Don't you think we might get in trouble for this?" "That's just crazy talk, Joe. Now hand me the water balloon with the methamphetamine in it before she's out of range."
