Cooking
I have no idea how to cook yet I have cooked almost every single dinner my family has ate for the past 2-3 years.
I mostly stick to preprepared garbage, like Tuna Helper, or these horrible Homestyle Bakes things. I've always wished my mother would stock up on more actual cooking supplies, other then the precooked things I have just described. Sometimes I cook a gourmet hamburger recipe that my father has secretly handed down to me, or pork chops though.
If being able to stick noodles in a pot and stir occasionally counts as cooking, I am the cooking king.
