She was Swiss or Dutch IIRC; was it Mariette Hartley?

Corect. Miss Hartley played Swedish surgeon Inga.

I liked it when she told Klinger she could arrange for him to have a sex change operation, and he said "YOU NEAN SOMEONE WOULD ACTUALLY TAKE A KNIFE AND...AND CUT OFF...AND PEOPLE CALL ME SICK"!!!

(the quote's not exact, I haven't seen the episode in a long time)

Thank you. I have enjoyed her work over the years.

At that time, Marriette Hartley was just EVERYWHERE...not surprisingly, she suffered from "overexposure" and her career died as quickly as it rose (Which is fine with me, I couldnt stand her)

there were so many girl's that Harkeye were flirting with

she wasn't just another fling, she was a visiting surgeon.
