I've been acquainted over the years with some "eccentric" physicians.
Recently a patient had a skin related concern (a basal cell cancer) and I needed to get him set up to see a dermatologist.
Me: Have you ever seen a dermatologist before?
Patient: Yes I have, but I can't remember his name, but I'll tell you this, when the two of us were in the exam room together, one of us was a little odd, and it wasn't me.
I immediately knew he was talking about. When I mentioned the doctors name he confirmed it.
He also agreed for me to get him back to see Dr. Odd again.
His description was right on the money and it helped to reconfirm that being odd is not always a bad thing, even in medicine!
