Just wondering what would happen if a metal container was used in a microwave, but grounded to the phono jack for the temperature probe. Assuming the connection was good, of course.

He meant to say 1/4 wavelength is around 3 cm. :) The wavelength is a few inches, like around 5 inches.

Actually, I was thinking x-band radar was very close to the microwave oven frequency. I was wrong.
The X band ranges from 7 to 12.5 GHz. The microwave ovens actually operate in the S band, the 10 cm radar band. The S band covers from 2 to 4 GHz.
According to

most microwave ovens operate on 2.45 GHz which gives 11.8 cm wavelength, 4.6 inches, for a quarter wave of a little over one inch or 2.95 cm
In any case, it is still a bad idea to put any metal bowls into your microwave over, unless the metal object has been designed for use in a microwave oven.
