years ago when I worked in a kitchen, there was this old lady, Ruth, who worked the fry station - she had hands like iron, could pick up things that came right out of the hot fat - fries, chicken tenders, shrimp, etc - decades of working with boiling oil gave her an almost superpower.

The one in the original picture still looks like a voltmeter probe, it has a rubber shaft all the way down until the last several mm, whereas the one in your picture has a much longer metal shaft before the tip as expected.

I think they're intentionally poking fun at the trope.
