Let the groaning begin!   

I invented a thought controlled air freshener. People say it's ridiculous, but it makes scents when you think about it.

I asked my doctor if I could administer my own anesthesia.

He said, "Sure.  Knock yourself out...."       

I used cryptocurrency to pay for my cryotherapy.  Now I'm broke because they froze my assets...

That's just cold man.
