128 fluid ounces

It's never a good idea to ask how many ounces your giant beer holds, especially when you plan on drinking 4 of them. Anyone know why? Yes, that's right. Because after you've downed 4 of the 25 oz. beers, instead of just saying, "Oh, I only had 4," you now have to acknowledge "I drank an amount of beer totaling just shy of a gallon."

And that ain't very ladylike.
