A number of years ago a new guy joined my work group. We were sitting in the staff room at lunch one day. I had just reheated my leftover spaghetti in the microwave, and was starting to eat when he quietly says, "you know, you're doing that wrong." I was flummoxed; what was I doing wrong? After some intense questioning, it turns out that he felt my Tupperware container was the wrong way to transport my leftovers, and the microwave was the wrong way to reheat it. The right way? Ziplock bag, then submerge it in boiling water, of course. This began many years of "you know, you're doing that wrong" jokes, even though he was actually not joking when he said it.
The moral of this story is, don't believe everyone who says you're doing it wrong... their way might be stupid.
