Drifting off the subject a bit......I do not use that phrase anymore.
About 15 years ago in my first day in a new job I walked into the secretary's office where she was speaking to a senior partner about organising a coprorate entertaining day involving racing cars. Being a friendly chap and keen to make a good impression I chipped in with "that sounds great, I'd give my right arm to do that."
I'll never forget the look of horror on the secretary's face and the glare I received from the senior partner...
It was at that point I noticed he was missing his right arm.
What are the chances of that!?!?!
