Well fine Sir, it just so happens that when I was in elementary school, about 10 years old, one of my favorite teachers wanted to teach us about humpback whales, and more generally math and science. It is fitting that we are now talking about whales on this platform, isn't it? ;) . Anyway, this awesome teacher had us watch episodes of "the Voyage of the Mimi" (https://en.wikipedia.org/wiki/The_Voyage_of_the_Mimi) and we learned quite a lot. Months later, the actual ship came to port in sunny Miami, FL and we went on a field trip to go see it. We got to meet the crew of the Mimi and ask them questions and sing pirate songs. The Shanty song that has stuck in my head all these years is called Drunken Sailor and I feel that is also quite fitting for you friend! Listen to it here:
Here's the most infamous pirate, Blackbeard:
His beard looks like it turned into dreadlocks , so he probably liked the ganja too!
Very excellent submission @nofiat!
