Preliminary sentence spoken by authority figure before any bizzare utterance to imply that any subsequent nonsensible ignorant ravings are just common sense irrespective of what the slaves to ‘Big Pharma’ keep saying.

I’m not a doctor, but X-rays, they cause mutations right? So why not expose people full of covideo19 viruses to a bunch of X-rays? Maybe we could turn the viruses into herpes, or something else harmless that we all have?

I dont know, I'm not a Doctor 

A sarcastic reply to a very obvious statement or situation.

Gerry: So you stayed up all night eh?
Phil: Yep and I feel really sleep deprived.
Gerry: Really? You know I heard sleep was a good way to treat sleep deprivation, but again I dont know, I'm not a doctor. I might be wrong.

Andrew: Hey look! It's raining outside!
John: Yea I heard it tends to happen every once and a while....but again I dont know, I'm not a doctor so don't take my word on that.
