You can if keep the n64 controller upside down

Same here, with the small difference that I use my right hand for you know what and I type with both hands (all ten fingers).

I only use my left hand when necessary. If I can use my right hand for it, I will always use my right hand.

So my left hand is completely unable to execute actions such as writing.

I do do everything better with my left. With one notable exception. It doesn't require much dexterity, so it makes sense in a way, but aside from that, why this one thing is right-dominant is bizarre. Beyond one reasonable theory, and another crackpot theory, I'm at a loss as to why this is the case. I've even tried different stimuli. Local weather girl. National weather girl. Weather Network weather girl. American Weather Network on Youtube. Same results.

I'm horrible at playing baseball because I catch and throw with my left hand. So when I catch using a glove, i'd have to take the glove off to throw.

I really need to learn to catch with my right...but I hardly play baseball anyways so oh wells :P

I shoot guns left handed and I believe when I was little I played tennis left handed because it came more naturally. I'm right handed for everything else to my knowledge. 

I can't beat my meat with my left hand, it just feels unnatural for me. Right hand is the right one :P
