Actually, if one looks at the Vostok ice core data, the position you enunciated, whether seriously or in jest, is perfectly reasonable. The Holocene interglacial has been going on about as long as a typical interglacial period. Quite frankly, we may wish for some anthropogenic global warming if the Holocene is running out.
It's more like an interglacial started up about 15,000 years ago, got slightly interrupted by the Younger Dryas event, then started back up and for some reason schmoozed over into an "interstadial" that would have popped up AFTER the beginning of the next major glacial period.
I think this happened in one of the earlier cycles so it looks like there was a 35,000 year interglacial even though it was just some start and stop interstadials combined with a normal interglacial.
All it takes is a change in a major ocean current to get an interstadial going.
It's not like the Earth flips from a period with massive glaciers to one without massive glaciers ~ there's a lot of back and forth. The main part is typified by large ice sheets over a good part of North America (otherwise called Canada). The interglacials are possibly warmer than any of the interstadials but last 10,000 + years.
