Final answer:
Dave Barry, a humorist who wrote for the Miami Herald, is the person credited with popularizing 'Talk Like a Pirate Day'. Neither Mark Twain nor Robert Wood were connected to this holiday, despite their reputations for humor.
Step-by-step explanation:
The humorist who wrote for the Miami Herald for over 20 years and popularized the fake holiday 'Talk Like a Pirate Day' is Dave Barry. Although Mark Twain was a well-known humorist, he was not responsible for this holiday. Similarly, while Robert Wood was known for his wit and mischief, he too was not involved in this holiday's creation. Dave Barry played a significant role in popularizing 'Talk Like a Pirate Day', which was invented in 1995 by John Baur and Mark Summers, known as Ol' Chumbucket and Cap'n Slappy. This joke holiday gained widespread attention after Barry mentioned it in one of his columns in the Miami Herald.
