Actually, I never did acrobatics in a 152, but there is a very important
secondary stall situation which every good flight instructor will warn you
about.

When recovering from the typical 152 stall you're still nose down and 
picking up speed.  Now, since you've been told that you should recover
in X feet and since you now have plenty of airspeed you horse that puppy
back up to straight and level again ***HONK*** stall in a nice straight
and level configuration that doesn't automatically fall forward like the
typical gentle 152 nose up stalls.
