18 Pars In A Round, in a Major...

It sounds more than plausible, but I also feel like there will always be one hole that ruins it, haha.

Googling it only gives you hits about Faldo's round. I could look through all major results if I have a spare FOREVER to do it. But wondered if anyone recalled it happening lately.

Basically, I would love to be able to tell this mate of mine that it hasn't happened since 1987 so he looks really silly, but it must have done at some point.
