I read the webcomic User Friendly every day, so I got a kick out of this one (click to see the whole comic):
I don't have 99 bucks for the last option, and honestly, $6 x 10^25 seems a bit pricey per mole^*. Avagadro's mole, that is, not Scarlett's. ^* Of course, it's only half that price per atom.
