Six people were taken into custody last night after making some... uhh... unauthorized changes to the famous Hollywood sign.

The LAPD apparently didn't appreciate the subtleties of the clearly brilliant joke.

The numbskull who arranged the stupid plan, was Jack Tenney, a rather popular YouTube prankster (he's got 5.5 million subscribers) who irritates people to get attention.

Basically, the worst kind of person.

Here's a Tweet from his management right after he and five of his buddies were arrested.

😩🤦‍♂️
