In every of the three seasons their occupation and location seems to be different. In the first season, they're zoo keepers, in the second they're musicians (though they play music throughout the entire series) and in the third they're working in a shop. Somehow they always end up having the strangest adventures.
The series is full of absurd humour, silly songs, sarcasm and wtf-moments. Howard's and Vince's interactions are often ridiculous (in the best way possible) and their contrasting personalities cause some very funny moments.
'The Mighty Boosh' is also a very goth-friendly series, I'm thinking of Vince's obsession with Gary Numan, an entire episode where Vince and Howard go goth to impress two goth girls, played by Dee Plume and Sue Denim, who make several appearances throughout the series, Chris Corner on the cover of several magazines (Noel Fielding played bass for IAMX for a while), an appearance of The Horrors and Howard that uses Goth Juice for his hair ("The most powerful hairspray known to man. Made from the tears of Robert Smith."). Vince's clothing style is also extremely extravagant and I admit, sometimes even inspiring.
So if you're a fan of British comedy, absurd humour, strange outfits, funny songs or quotable dialogues, you should definitely give 'The Mighty Boosh' a try. It's one of the most amusing series I've watched in a very long time.
Here's a couple of clips I found on YouTube, enjoy!
