"I Swear, I have No Idea"

You may heard this phrase before somewhere else or even you yourself used it. Anyways, there's nothing special about this post. This is simply because I got nothing else to post. So basically this come out from nonsense. LOL! 

I just overheard this phrase today and I think it felt like I needed to react to this because, for me, this is an overly used phrase just to escape from the situation. 

Really? No idea? So you want me to buy that?
