Just remembered a funny moment.

Once I was talking to a director of an oncology center. We were talking about Varian linear accelerators (it's a device used for cancer radiation therapy). I had no idea about the brand names of these devices at the time and thought we were talking about ovarian linear accelerators (i.e. radiation therapy for ovarian cancers).

:) It was a brief embarrassing moment at the time but it worked out OK in the end.

I remembered this incident when came across a Varian ad on LinkedIn.
