When I was practicing for my CFI ride, I was doing cross-controlled stalls
in an Arrow. Once you get over the initial concept that you're
intentionally trying to do what you've always been taught you're never
supposed to do, you quickly discover that (at least in an Arrow), it's
almost impossible to get the damn thing to actually stall like that. Full
rudder, full opposite ailerion, idle power, and full back elevator. The
damn thing just sort of slowly yaws (pro-rudder, as I remember), and mushes
like a wounded duck with its nose up the air.
Well, except for the one time that I did actually manage to get it to
stall. That was a little more exciting. My first indication that
something was wrong was when my flight bag went bouncing off the cabin
ceiling :-)

Do that in a Tcraft or a Cessna 170 and you will be on your back before
you can stop your eyeballs on the horizon. It is called a snap- (or
flick-) roll. If you do not know how to fly inverted or recover from
inverted spins, you don't want to explore the possibility.
