Whats Wrong with French People?

[Wooglin]

i have recently come across the following classifactions for champagne bottle size:

Quarter-Bottle--6.3 fluid ounces
Half-Bottle--12.7 fluid ounces
Bottle--25.4 fluid ounces
Magnum--50.8 fluid ounces--2 bottles
Jeroboam--101.6 fluid ounces--4 bottles
Rehoboam--147 fluid ounces--6 bottles
Methuselah--196 fluid ounces--8 bottles
Salmanazar--304.8 fluid ounces--12 bottles
Balthazar--406.4 fluid ounces--16 bottles
Nebuchadnezzar--508 fluid ounces--20 bottles

what gives with these wack-job terms? sounds like the naming sessions came after a few too many jeroboams of brut if u ask me. maybe this has some correlation to other idiosynchrosis of these chain-smoking non-showering jerry lewis-loving folk. anybody have any ideas?
