The Sims 2 Glitches

Skills up 3 pionts
Alright i'm here trying to make Combo Pizza and i get Turkey+Tomato+Cheese+Whole wheat Flour and I didn't look at the recipe for Combo Pizza and I make Chefs Salad (this was on Free Play Mode) and eat it ! time and it put me up 3 skills points I eat it again (so I know I can put it on neoseeker cheats) and then it took away my 3 skill points. Well hope you guys like it.
