Oh, yeah, the “jog” in the Massachusetts-Connecticut border is, according to legend, to keep Mass. from sliding into the Atlantic Ocean. The real story is just too dull.
Also, a small chunk of the Borough of Manhattan (Marble Hill) is actually on the mainland, attached to the Bronx, where a side channel of the Harlem River was filled in around a former island.
Burma and Thailand have fought each other for centuries if not longer. Bangkok is the capitol of Thailand mainly because Ayutthya and Sukothai were sacked so often. They still don’t get along too well and IIRC still have border skirmishes in the northern mountain areas of Thailand where a lot of ethnic tribes (the Karen and related tribes) dwell and the opium trade thrives.
Did you mention Maryland or did I miss it?
USA is dissjoint within the same contiguous land mass. ie you can travel from Alaska to the rest of mainland USA br land, but not without going through another country. I can’t think offhand of any other country with such a break in its shape.
I live here - there’s a peculair jigsaw-notch piece of the west of the county, which takes in the town of Newmarket. I’ve never found out why this border occurred.
The US has two other disjoint parts, where you can only travel to the rest of the US by land by travelling through Canada: Point Roberts in Washington State, and the Northwest Angle of Minnesota (already mentioned).
Because that area was settled by Virginia before Maryland became a colony.
Similar to the Northwest Angle is Point Roberts, WA. It’s part of the U.S. because it’s below the 49th parallel, but it’s reachable by land only through Canada.
Brunei is also non-conguous within one land mass: http://www.brudirect.com/BruneiInfo/info/brudirect__location3.htm
*non-contiguous
There are many, categorized as enclaves.
Fishers Island, NY looks like it should be part of Connecticut. You cannot reach it by car without going through CT, and it’s considrably closer to New London than anywhere in NY. It was granted to NY in the late 1800s, and there’s a small movement right now to join CT.
Also Angola and it’s slightly detached Cabinda province…
Your own link excludes the American examples from being considered true enclaves!
Oh, I can think of one more 
Thanks exclaves is my new word for the day.
The Izu Islands and Ogasawara Islands, stretching out over a distance of 1,850 kilometers south of Tokyo in the Pacific Ocean, are actually considered part of Tokyo metropolis, and governed by Tokyo Metropolitan Government
If you’re thinking of Hawaii, can you explain how you can travel from Hawaii to the lower 48 by land through Canada? And if Hawaii, why not other parts of the US which are islands? (e.g., the Channel Islands of California)
One not mentioned so far: Afghanistan’s Wakhan Corridor, across the northern end of Pakistan to connect with China, was created by the British in the 19th century as a buffer against Russian adventurism into India.
Here’s a recent thread on the subject.
