I am a ‘big’ man and I would say that where things peaked in American culture as far as ridiculous sizes go was when a Starbucks-like chain operating in Florida was offering a 42-ounce version of a frappucino-type drink that Starbucks only provided a 24-ounce version of, this was shortly before Super Size Me came out which started to change the culture on those things.

I realize most of these are from gas stations, but most fast food sodas are like a third to a half way filled with ice lol.
