Cuisinart frozen yogurt...or not

so today Pie comes home from his gig and asks for the ice cream maker...brought fixings for making frozen yogurt. whoopie! we get to use our ice cream maker for the first time. we blend the frozen strawberries, measure out the yogurt, pour everything nicely into the ice cream maker bowl. it's on...we sent the timer to 20 minutes, and watch the whole ten yards while waiting. 20 minutes is up, the mixture isn't even cold! take out instruction manual....we were supposed to freeze the bowl! ha! so we end up with strawberry yogurt smoothies instead. delicious, too!
