John Milkovisch, this Bud's for you. The late railroad worker got bored in retirement and found the cure for what aled him: transforming his suburban Houston home into an homage to hops and barley. Starting in 1968, Milkovisch spent the next 18 years turning beer cans into siding, curtains, walls, and decorations. Getting the 39,000 cans required drinking a six-pack a day, but Milkovisch never wavered in his magnificent obsession. 222 Malone Street, Houston, Texas

GO  TO  EXTREMES

UDDERLY FASCINATING
Go to Harvard and what do you get? A close-up view of a fiberglass cow, of course. If you want an Ivy League education, you'll have to hoof it to Massachusetts. But in Harvard, Illinois, you'll find Harmilda the cow, four-legged icon of the town's annual Harvard Milk Days. Born in 1970, Harmilda proudly stands over a plaque that proclaims Harvard as "the Milk Center of the World." If you've figured out that Harmilda's name is a shortened version of Harvard Milk Days, you may have a good shot at getting into that other Harvard. Intersection of Highway 14 and Highway 173, Harvard, Illinois

WORLD'S LARGEST PRAIRIE CHICKEN
Before mild-mannered and super-polite Nordic types took over Minnesota, the state was populated by a lot of prairie chickens. As the Prairie Chicken Capital of Minnesota, the city of Rothsay knew the only decent thing to do was to erect a 9,000-pound statue of the diminutive bird, which it did in 1976. Intersection of Interstate 94 and Center Street, Rothsay, Minnesota

WORLD'S LARGEST FLAG
You have to love a guy who had a tattoo of the U.S. flag imprinted on his chest, a scar serving as the flagpole. The late Thomas Demski owned Superflag, a behemoth star-spangled banner that measures 505 feet by 225 feet and weighs 3,000 pounds. Even if you never get to the Superflag Company in Long Beach, California, you still might have a chance to see Superflag, which has been displayed at Super Bowls, national monuments, and the Hoover Dam. 402 Lime Avenue, Long Beach, California; www.superflag.com

WORLD'S LARGEST STOVE
We're not sure where the world's largest microwave is, but its old-school predecessor resides in Detroit. The Michigan Stove Company wanted to make a big splash at the Chicago World's Fair of 1893, so it whipped up this monster (25 feet tall, 30 feet long, and 20 feet wide) in a jiffy. Michigan State Fairgrounds, 1120 West State Fair Avenue, Detroit, Michigan

OREGON VORTEX
Don't go to this Gold Hill, Oregon, attraction unless you're prepared to be stupefied. True believers claim the structure is swimming in paranormal properties and that it sets the law of gravity on its head. Killjoys will point out the clever optical illusions that make this sight a weird, wild experience. 4303 Left Fork Sardine Creek Road, Gold Hill, Oregon; www.oregonvortex.com

WORLD'S LARGEST BALL OF STAMPS
In the early 1950s, some enterprising lads at the famed Boys Town orphanage near Omaha, Nebraska, had some extra time on their hands. The PlayStation was still 40 years in the future, so they started licking stamps. How many? Nobody knows for sure. But the insanity ended only after a 600-pound sphere was created. Frankly, that’s the best story we’ve heard philately. Leon Myers Stamp Center, 13628 Flanagan Boulevard, Boys Town, Nebraska

WORLD’S LARGEST FRYING PAN
In 1950, the Mumford Sheet Metal Works in Selbyville, Delaware, designed and built Colonel Sanders’s greatest fantasy — a 10-foot-diameter frying pan — for the Delmarva Chicken Festival. Delaware History Museum, 504 Market Street, Wilmington, Delaware

WORLD’S OLDEST WORKING LIGHTBULB
Depending on whose story you believe, the world’s oldest working lightbulb first started shining in 1901, 1902, or 1905. But, you know, after a century, does it really matter? Of course not. What matters is that Livermore (California) Fire Department Station No. 6 can brag about being in Guinness World Records and you probably can’t. 4550 East Avenue, Livermore, California; www.centennialbulb.org
