I'm just going to pretend (Dr. House meme)

In reality, I have no idea what you're talking about, but I'll just pretend like I do. Will that make you feel better?

"I'm just going to pretend to know what you're talking about".

That's Dr. House, for you. He really knows what you're talking about, or at least he's acting like he does. 

When you just hold up two thumbs and just say "Ok." Can you relate to this? This meme really makes you laugh.
