What name connects a football team whose name got longer in the 1990s, an actress who has been in two different TV series centring on prostitution, and a feature of between a third and a half of human feet, including those of the Statue of Liberty?

Must be Morton

Greenock Morton

Samantha Morton

Morton's Toe

Indeed. The longest name in Scottish football, Inverness Caledonian Thistle was formed when Inverness Thistle and Caledonian Thistle merged in 1994. In the same year, the 1874 club Morton changed its name to Greenock Morton to celebrate the links with its home town.
Samantha Morton has acted with Tom Cruise in "Minority Report", but one of her early roles was in ITV's "Band of Gold" (1995-1997) as a young prostitute in Bradford's red-light district. In 2017, she played a madam of an 18th century London brothel in the saucy costume drama "Harlots".
A US orthopaedic surgeon called Dudley Joy Morton's name was given to Morton's toe, the condition where the second toe is longer than the big toe. The first source I read said this occurs in 40 per cent of people, but that appears to be a gross overexageration, with figures thought to be nearer 20%, Because it was regarded as a male beauty ideal in Ancient Greece and appears in their statues, it is sometimes called Greek toe. This has continued into neoclassical works such as the Statue of Liberty.

I could have also included Morton's fork, a false choice where each decision leads to the same conclusion, often nasty.

Here are some explanations of Dizart's answers:

Morton's toe, where the second toe is longer than the big toe, occurs in roughly 30-50% of people and is famously seen on the Statue of Liberty.
