[On tree-ring dating]
Wonder how much the guy who kept track of all of the tree's birthdays got paid? He was there when it was just a seed, right?

Look it's simple, your grow stupider every year, trees grow bigger every year. Deciduous trees grow in cycles depending upon the seasons, just as you grow stupider in spurts, usually around Christmas and Easter.
Now Spring comes once a year, so you can tell how many Springs this tree has known.

We have observed the effect (tree-ring growth) in younger trees whose ages are known through other methods. We understand why a ring would be added every spring. Hence, it is reasonable to conclude that at the very least, we aren't far off with older trees if we keep track of their ages the same way (seasonal variation plus the possibility of a \"false spring\" weather pattern means we can't be certain of the exact number, but we can be pretty confident that we're within a few years).
