According to Ripley's Believe It or Not, Williams, a Toronto resident, plans to walk 32 miles to Oakville, Ontario, to his favorite bar before he imbibes.
Even more unbelievable: the Oakville Beaver reports that is the 35th year in a row that Williams has made the tippling trek.
The tradition supposedly originated in prohibition days when a group of Irish friends walked to Oakville -- the only place they could get a pint of beer.
Time has marched on, but Williams keeps up the walk anyway. However, it's presumed he has a designated driver -- or at least a designated "piggy backer" -- when he goes home.
Williams has a unique way of celebrating St. Paddy's Day, but the unusual seems to become the usual on March 17.
For instance, while there will be hundreds of parades, organizers would have to go to great lengths to "out-weird" the one in Maryville, Mo.: It's the world's shortest annual St. Patrick's Day parade, measuring only 99.9 feet.
And while the ostensible purpose of the day is to honor St. Patrick, who, legend has it, drove the snakes out of Ireland, McCormick & Schmick's Seafood Restaurant in Las Vegas prefers to honor the cab drivers who transport the high rollers around Sin City.
The restaurant will honor the hacks with "St. Cabby's Day," during which they will be feted with a buffet-style breakfast, complete with green eggs and ham and Lucky Charms cereal.
This is the seventh year the restaurant has held the event, and about 500 cab drivers are expected to attend.
But not all March 17 celebrations will center on Ireland's patron saint. At least one will be focused on a pill dispenser.
Three years ago, on St. Patrick's Day, Milford Regional Medical Center in Milford, Mass., implemented a device that ensures that patients receive the right medication at the right time.
Supposedly, "Paddy" has increased the pharmacy's efficiency allowing staff to spend more time for other tasks and, as a result, the Medical Center celebrates each St. Patrick's Day with a big shindig.
Food and cake will be served, but unlike other St. Patrick's celebrations, there won't be any Guinness.
But that's to be expected: Paddy, after all, is only three.
