This line was also referenced in the TV sit-com Malcolm in the Middle
, when Francis is challenged by his peers at military school
with 'no man can eat 100 quacks
The quacks in question (commonly known as peeps) are those florescent yellow and pink molded-marshmallow chicks, adding in a little 'chicken or the egg' thema to the reference.
Francis, unable to turn down any dare
, proceeds to eat 100 of them to everyone's amazement.
