Yeah, there are any number of "But so-and-so did it so much better than the Beatles!" instances, but the thing is that so-and-so wouldn't have even tried if the Beatles hadn't done it first.
Take or leave their music, there's no denying the massive influence they had.
Your average shoebox is 35X23.5X13.5 cm, or 11103.75 cubic centimeters. The density of gold is 19.3 g/cm^3. You can fit 11103.75X19.3 = 214302 grams of gold in a shoebox. One gram of gold right now is $77.78 US. That's 214302X77.78 = over 16.5 million US. There are things significantly more valuable (but not more fungible) than gold, too. The Pi million pill is completely moot. Or just take both, I guess.
