I've always found that strange since that particular way of doing "hamburger" was pretty much the cheap crappy "you don't get real burgers today just this thin thing and some mashed powder potatoes on the side" day at the cafeteria throughout primary and secondary school. It feels like the leftovers you're not too sure about.
It's like they're all saying their favorite bread is "we forgot to put it away properly and now it's stale".
