I have always felt that Kobayashi downing 8 kilos plus of Cow Brains the most "unbreakable" record.
Greatest feat I've seen...17 glasses(6 oz portions)of red wine with out leaving the barstool, and the drinker paid the tab got up and walked out the door with out stopping at the mens room.I do not have an exact time but less than 4 hours I'm sure.P.S. After the 16th glass(a house byback) He said I was going to go after this one ,my girl is waiting for me, but I'll have to have one more because it is impolite to leave after a byback. Tipped better than 20% too! Never saw the average sized guy before or after.
