The Constitution of the Hash House Harriers is laid out in the following philosophy from a KL city club registration card dated 1950:
To promote physical fitness among our members
To get rid of weekend hangovers
To acquire a good thirst and to satisfy it in beer
To persuade the older members that they are not as old as they feel
I'm not sure they thought number two and number three through carefully... Although, maybe that's why there are 3-4 each weekend in Seoul...
